cos(pi/2) = 0
so answer is pi/4
Hey, I would like you guys to check over my answer as it seems a little bit odd to me.
The question is to find the equation of a tangent. So far, I've got the derivative.
y' = xy/2 + pi(cos(y))
So to get the slope, I've substituted x and y with a point (1, pi/2)
I've managed to get:
Is that correct?
