| April 25, 2021 | education
Given a function:
y = sin x.
To find the intervals of increase of the function, we find its derivative:
y ‘= cos x.
the function increases where its derivative is positive.
We solve the inequality:
cos x> 0;
We get:
-п / 2 + 2 * п * N <x <п / 2 + 2 * п * N, where N is an integer.
