C3 Differentiation question help :)
The maximum point on the curve with the equation y=x(sqrtsinx)
0<x<pi
is the point A.
Show that the x coordinate of point A satisfies the equation:
2tanx + x =O
I have started this off my differentiating the equation and making it equal to zero. I got:
sinx^-1/2 (sinx + 1/2xcosx) =0
But don't know where to go from here.
Tried to equal sinx^-1/2 to O and then other part to zero, but how can you solve the 2nd part?
Thanks
