I have this question in which I know I probably have to use implicit differentiation but I have no idea how to do this can someone give me a hint to get started. all the implicit differentiation problems I have done only have a combination of x and y but this one has x, y and t.(adsbygoogle = window.adsbygoogle || []).push({});

find dy/dx for x = 4sint, y= 4cost

thanks in advance...
