Question #ec230

1 Answer

Jan 3, 2016

$cos (x + a)$ $cos(x+a)$

Explanation:

We can find the derivative using the Chain Rule:

Let $θ = (x + a)$ $theta=(x+a)$

Derivative of $sin θ = cos θ$ $sintheta=costheta$
Derivative of $(x + a) = 1 + 0 = 1$ $(x+a)=1+0=1$

Therefore, derivative of $sin (x + a) = cos (x + a) \cdot 1 = cos (x + a)$ $sin(x+a)=cos(x+a)*1=cos(x+a)$
