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.

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) ## What is an identity, and how do I prove it?

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) = Decide math questions
