Find the derivative of y with respect to x:
y=(1+cos²x)^6
y'=6(1+cos²x)^5
How do you derive inside the brackets? The answer says -sin2x, but wouldn't it be -2sinx, using the chain rule.

determine f'( x )
To calculate these derivatives we use the Power Rule and the Chain Rule: \begin{aligned}<br /> \frac{d}{dx}x^n&=nx^{n-1}\\<br /> \frac{d}{dx}f(g(x))&=f'(g(x))g'(x).<br /> \end{aligned} For example, $
\frac{d}{dx}(\ln x)^5=5(\ln x)^4\frac{d}{dx}\ln x.$

Prove cos(pi-x)=cos(pi+x)=-cosx? - Homework Help - eNotes.com
Prove cos(pi-x)=cos(pi+x)=-cosx?
To prove the providedexpression, we'll use the identities:
cos (a+b) = cos a*cos b - sin a*sin b
cos (a-b) = cos a*cos b + sin a*sin b
Let a = `Pi` and b = x
cos (`Pi`-x) = cos `Pi`*cos x + sin `Pi`*sin x
But cos `Pi` =... | 4 | [
