As the students explain their observations I write their reasons beside the step on the board see page 2 of bell cofunction. After analyzing the process I ask "Was the process easy to follow? Why or Why not? This worksheet has students find the trigonometric values of complementary angles and then determine which function values are equal.

I remind students to have their calculators in degree mode for this activity. I used degrees in the activity because students will have an easier time noticing that the angles in the tables are complementary.

As students work I move around and answer questions. The main question I expect is, "How do I input cotangent, secant and cosecant into my calculator?

After students have worked for 10 minutes, we go over the Questions On Question 3, I ask the students to focus on the first table. We will work together to write down all the function values that are equivalent.

Usually, my students see the pattern. I ask, "If I know the value of sin 75 what else will I know? I then discuss why the functions cosine, cotangent and cosecant have these names. I say something to the effect that the sin theta has the same value as the cosine of the complement of theta. I write this statement on the board so students can think about the statement.

We then write a similar statement for tangent and secant. I know that some students are still a little confused and I need to develop a method for writing the complement of an angle. I draw a right triangle on the board and have the students determine sin A and cos B.

This helps students see that the ratios are equivalent.

I ask, "What do you know about angle A and angle B? I expect them to use one of two different ideas to explain their choice. Some will say all the angles add to degrees and angle C is 90 so angle A and angle B add to Others remember that the acute angles of a right triangle are complementary. I then ask "how can you compute the complement of an angle?

We also write the expression in terms of angle B to make sure students see both equations. In work related applications, it is often necessary to work with real number values instead of degrees as angle measurements. This is a good point to remind students that we have 2 ways to measure angles, degrees and radians.Test and Worksheet Generators for Math Teachers.

You have to rely on your existing customers to review your company and create a positive influence for prospective customers. The best way to generate social proof is by getting your customers to review your products. First, make sure you focus on the customer experience. Let them review your company on Facebook. Ultimately, this can increase your conversions.

Having lots of options for your customers to rate your business on multiple platforms is a great way to increase the number of reviews and to generate some social proof. Etsy asked their customers to leave a review with a follow-up email or text message. All they needed to do was just ask. To keep everything relevant, Etsy allows customers to review products within 100 days of their purchase.

Giving your customers a timeline to make a verified review is a great way to prove the legitimacy of their purchase and opinion. Amazon highlights all of their verified purchases. In fact, bad experiences are two to three times more likely to get reviewed.

They can simply click the link on your website, and it will bring them directly to the review form on another platform, like TripAdvisor.

Include a link on emails asking for feedback. You just need to make sure the subject line of your email generates a high open rate. There is a direct correlation between click rates and open rates. If the link brings them to a review page, that increases the chances of the customer leaving a review.

We strive to be the best (type of business) in (name of your city). Respond to positive reviews. In the example above, the reply addressed the reviewer directly, instead of just a generic response.

The positive recognition may even entice this customer to leave reviews on other platforms as well. Earlier we looked at an example where the reviewer mentioned a positive experience with an employee by name. If your staff is doing a bad job, they could risk getting blasted online by a disgruntled customer.

Regular conversations with your staff about the goals and mission of your company will keep your employees engaged. Make sure your customer service staff is promoting online reviews to your clientele after each transaction.

Ask your customers to fill out a survey. They also make it really easy for you to integrate the links with your email campaigns or social media marketing strategies.

You can do this on your website, as well. If customers are willing to give your company a testimonial, ask them if you can include a high-quality photo.

You can use storytelling to increase your conversions. Encourage your customers to tell a story about their experience. Prospective customers can really get a glimpse of what to expect if they visit this restaurant, all based on the review above. Find a chiropractor to generate social proof by saying your chairs have enough lumbar support for people with sore backs. Look how Tesla used crowds to generate social proof.No idea if that is actually possible with the unreleased ships left, though.

Something exotic like the Atlanta, that doesn't play like 'regular' ships. And if they ut in battlecruiers like the Renown i would not be surprised of we get to see a package with Repulse and Prince of Wales at the end of next year.

S Philadelphia - Brooklyn class cruiser (Basically a Cleveland with an extra turret) - Served in the US navy earning multiple battle stars and citations. Later spent 20 years in the Brazilian Navy. With 12 (4x3 turret lay out) 12" guns, she'd likely fit in at T4 or 5 quite well, depending on design. I sincerely doubt WG will do an Austrian line, so she won't be stealing from anyone's tech tree ships.

I would also love Tosa as a t8 IJN ship. Basically just a fatter, slower Amagi. I'd also join the chorus for the usual. Akagi, Enterprise, Hood, and a Regina Marina ship of choice. I'd personally lean for Littorio but that's just Kancolle fandom talking.

And yeah we'd better get either Shigure or Yuudachi as a T7 premium. While Shigure is best girl I'd be happy with either. Adding on to the weeab premium boats, I also hope we see Harekaze at T8. I wasn't the biggest fan of Haifuri, but it was good enough, and the idea of a Kagero with the options for either Akizuki's or American guns sounds like it'd be great fun gameplay wise.

Possibly Vanguard as a Tier VIII. I'm hoping the Frenchies and Italians playing this game get ATLEAST one each, I'm not super knowledgable about either of these, but it's fairly obvious which ships COULD be a premium this year (plenty named in this thread alone).

A competitive Tier VIII USN. Which'll probably be the Alabama. And no more Russian Premiums for a year except maybe a BB one other than Nikolai, they had plenty as of late, at this rate they'll have an additional tech tree of Premiums before major navies get their silver tech trees. Since I'm really not sure whether i should buy the tirpitz or not right now.

And 5 special paint jobs. And a polar bear as captain. But it plays alone against everyone else (or with a few Tier I ships for the lolz of confused Tier I players wondering what the hell just happened). One of the Fantasque-class destroyers could be a pretty good premium, maybe Le Terrible since I assume Fantasque herself would be a tech tree ship and also WG selling a Terrible premium would amuse me.

Ridiculously fast (45kt), cruiser-sized, heavily armored and with pretty good torpedoes. Also, I'd love to see more pre-dreadnought battleships. And to add the imperial russian black-and-yellow paint scheme for russian ships.Getting the app setup in your store is effortless.
