Trigonometry Identities

Hi,

Thank you so much for letting us know what you would like to see added to the site! Our team is always looking to add content that will help our users reach their educational goals, so your feedback is incredibly helpful.

Thank you again!

I agree. To be more specific I would like to see more examples of basic trig identities such as the reciprocal and quotient identities. I find that it is very helpful for students to conquer these two skills before going further into the trig identities. Would you consider adding this?

Also, after that is a good time to verify basic trig identities before moving into the more complex trig identity problems.

I can confirm now, the lack of sufficient trig knowledge hurts later on in Calculus. I'm just staring clueless at the exercises and their solutions. After stubborn headbutting with these specific exercises I'm forced to skip and abandon them because as it is right now, they are impossible. I really hope this won't come to bite me later on. Trig remains about the only area where I still need to look up the formula sheets every time I deal with it. I really hope it won't happen but that kind of things may make me resort to just resenting Trig.

Overall, both the technical and the design parts of Khan Academy are pretty good. Even though I wouldn't personally agree with some of the UI placement decisions, I haven't seen any user Khan Academy reviews that would be upset with the things to do in Bhutan. The user interface is easy to use, simple and clear.
