# smallest positive value? watch

find the smallest positive values for the following when the gradient is equal to the corresponding value

y= theta + sin theta ; 3/2

and

y = sin (2theta) -3cos (2theta); 0

My answer: theta = 80.8 degrees.

are these correct??

Thanks

I agree with the second one but get 120 degrees for the first
