Question

03. Differentiate the following functions :
(a) sin 2x​

Answer 1

Answer:

We have that u=sin(x), so differentiating u with respect to x we have that du/dx=cos(x). Now we simply substitute the values of dy/du and du/dx into the chain rule so that we can obtain a value for dy/dx. We have that dy/dx = dy/du x du/dx, so dy/dx = 2ucos(x).
