The derivative of sine squared can be determined by using the chain rule. Under the chain rule, the equation becomes two times the sine of x times the derivative of the sine of x. The derivative of the sine of x is the cosine of x, resulting in the formula 2sin(x)cos(x). The formula 2sin(x)cos(x) can be simplified down to the sine of two times ...

Best Answer: sin^2(x) = (sin x)^2 To find the derivative you need to use the chain rule. The derivative is: 2 (sin x) (cos x) How I found it: The 2 is the derivative of the outer function times what was inside (sin x). then take the derivtive of the inner function (sin x) which is (cos x) Derivative of cos ...

The derivative of sin x is cos x, The derivative of cos x is −sin x (note the negative sign!) and The derivative of tan x is sec 2 x. Now, if u = f(x) is a function of x, then by using the chain rule, we have: `(d(sin u))/(dx)=cos u(du)/(dx)` ... Derivative of square root of sine x by first principles.

f(x) = (sin x) 2 can be written as f(u) = u 2 where u = sin x. f´(u) = 2u and u´= cos x so that multiplying together we get f´(x) = 2u·cos x = 2 sin x cos x. The Cha in Rule states that to differentiate a composite function we differentiate the outer function and multiply by the derivative of the inner function. Example 2 +
