Question

sin(2x+1) find the derivative of x​

Answer 1

Explanation:

Say if the problem y=sin(ax+b)

Then you can find the derivative of this using chain rule.

dydx=cos(ax+b)⋅ddx(ax+b)

dydx=cos(ax+b)(a)

dydx=acos(ax+b)

Similarly

y=sin(2x+1)

dydx=cos(2x+1)ddx(2x+1)

dydx=cos(2x+1)(2)

dydx=2cos(2x+1) Answer
