Formulae of "The derivatives of Trigonometric Functions "
Illustrative Examples
Find the first derivative of the given trigonometric function.In the given example y = sin 5x, u = 5x. We can use the relationship "i" provided above.
Above show the first approach as we derive the u.
Having the relationship derivative of sinu = cosu.
Arrived at the final answer.
