SUMMARY
The discussion focuses on finding the first and second derivatives, dy/dx and d²y/dx², for the parametric equations x = cos(3t) and y = (sin(3t))². The derivatives are calculated using the chain rule, where dy/dx is derived from the ratio (dy/dt)/(dx/dt). The specific derivatives are dx/dt = -3sin(3t) and dy/dt = 6sin(3t)cos(3t), confirming the application of Leibniz notation in this context.
