dy/dx= cosx + sinx

In first quadrant both are positive so increasing
In second quadrant sinx is positive but cos x is negative
till 135 magnitude of sinx > cosx so it will be positive
Increasing till 135

It will be negative from 135-180 in second quadrant

Accordingly you can find for 3rd and 4th quadrant.
