Hi all i have a calculus problem Differentiate with respect to the variable y=1/3cos-1(x/4) i completed this using the inverse cosine function y=cos-1(x^-4)/3 function -1/root a^2-x^2 Differentiated dy/dx=(1/root4^2-x^2)/3 Brought in the 3 for dy/dx=0.3x(1/root4^2-x^2) at this point i cant really see how to simplify this further. Can it be done. are the current steps correct? Thank you
