Hi, I've been stuck on this question for the past 30 mins:
A curve is given by the parametric equations:
x=4Sin^3(t) y=cos(2t)
Show that dx/dy = -3sin(t)
I've tried (dx/dt)/(dy/dt) method and changing x into 3sint -sin3t to be able to differentiate. I've also tried substitution. These methods don't seem to work and I need a bit of help. Any help offered appreciated. Thanks!
