Do you need help with your math homework? Are you struggling to understand concepts How to prove trig identities?

Solve Now
The first equation below is the most important one to know, and you’ll see it often when using trig identities. s i n 2 ( θ) + c o s 2 ( θ) = 1 t a n 2 ( θ) + 1 = s e c 2 ( θ) 1 + c o t 2 ( θ)

In order to prove trigonometric identities, we generally use other known identities such as Pythagorean identities. Prove that (1 - \sin x) (1 +\csc x) =\cos x \cot x. (1−sinx)(1+cscx) =

This app is amazing, I use it at school to double check work and if I have done something wrong, I can check the steps and see where I went wrong, the app is super useful when I dont understand how to complete and problem, or where I may have gone wrong on one.

Very good app and the explanation is pretty accurate and the calculator has almost everything so u can put anything alomst, i've attempted my math course three times and I'm on my 4th attempt now, really helps me calculate things due to the fact that I don't have a scientific calculator at home.

Very useful app for my Algebra 1 and 2 students. You can even take a picture of your math home work and it will do it for you, i love this app! It's very easy to use, just take a picture and it gives you the answer as well as the explanation to solve the problem.
