Question

The answer of cos thetha•dthetha=?

Answer 1

Answer:

sinθ

Explanation:

Dear student, I suppose that the Question is of integration

We know that differentiation of ,

$\frac{d( \sin(theta ) )}{d \: theta} = \cos(theta)$

On cross multiplying we get,

$d( \sin(theta) ) = cos(theta)d \: theta$We also know that integration is reverse of differentiation

therefore on integrating it we get

integral of cosθdθ= sinθ+c (where c is an arbitrary constant)

Hope it helps you!!
