2020-09-25 · Using the product rule, the derivative of cos^2x is -sin(2x) Finding the derivative of cos^2x using the chain rule. The chain rule is useful for finding the derivative of a function which could have been differentiated had it been in x, but it is in the form of another expression which could also be differentiated if it stood on its own.

IMHO you are not the only one and not totally at fault to be confused - sin 2 x as far as I can see is a sort of mathematical slang, not strictly logical (so no wonder your calculator doesn't understand it either) which by its antiquity is let through and is universal - so there it is to get used to. How to integrate sin^2 x using the addition formula for cos(2x) and a trigonometric identity. 2020-09-09 · We can write sin 2 x as (sin(x)) 2. Now the function is in the form of x 2, except it does not have x as the base, instead it has another function of x (sin(x)) as the base. Let’s call the function of the base g(x), which means: g(x) = sin(x) From this it follows that: sin(x) 2 = g(x) 2 sin ^2 (x) + cos ^2 (x) = 1 . tan ^2 (x) + 1 = sec ^2 (x) . cot ^2 (x) + 1 = csc ^2 (x) .
