Why didn't you do the normal way of differentiation. UV method?

#

See, both the denominators will cancel

to what yazim said by chain rule:

dy/dx = dy/dt * dt/dx

find dy/dt
find dx/dt then take the reciprocal
multiply both results

#

cos2t cancels out

#

i didnt simplify the rest but i think this could be a good way to do it
