    Can someone please verify whether my answers are correct please?

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

    y= theta + sin theta ; 3/2

    My answer: theta= 60 degrees.

    and

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

    My answer: theta = 80.8 degrees.

    are these correct??

    Thanks
