Question

What is the derivative of `sin 5x`?

Answer 1

`5cos(5x)`

Explanation:

By the chain rule we get
`cos(5x)*5`

Answer 2

`5cos5x`

Explanation:

`"differentiate using the "color(blue)"chain rule"`

`"given "y=f(g(x))" then"`

`dy/dx=f'(g(x))xxg'(x)larrcolor(blue)"chain rule"`

`d/dx(sin5x)=cos5x xxd/dx(5x)=5cos5x`
