Consider the function f(x,y)=x^2+y^2 where x=sin2θ and y=cos2θ
df/dθ is given by?
Will someone be kind enough to provide me with the complete answer and explanation please?
I have studied stuff like this in 8 years.I've running around this for the past three days.
I have looked at the chain rule for multivariate functions.
The Trig identity Sin^2+Cos^2=1
I seem to be moving in circles
