F(x) = (pi)3x -sin(pi)x3 for the left part, use rule:d/dx(au)= au*lna*du/dx for right part apply productrule: f '(x)= (pi)3x*ln[pi]*d/dx(3x)-[x3cos(pi)+sin(pi)3x2] =3(pi)3xln[pi]-x3cos(pi)-sin(pi)3x2

If your fuction is π3x-sin(πx3) then the derivative is 3(π3x / lnπ) -(3πx2)cos(πx3)

π3x- sin(πx3) treat them separetely: π3x u=3x u1=3 so 3π3x -sinπx3 chain rule d/dx sin u = cosu*u1 so, -cosπx3(π3x2)
