Question

find the derivative of Sin (x+a) ...!

Answer 1

Using the limit laws, and remembering that sin(x) are cos(x) are constant as h approaches zero, we find the derivative of the sine function as follows. Our second basic differentiation formula provides the slope of this tangent line; the slope is the value of the derivative at /3, namely cos( /3).

Answer 2

d(x+a)/dxCos(x+a) of a is constant its cos(x+a)
