y = 3^(xsinx)
lny = ln3^(xsinx)
lny = xsinx(ln3) = ln3 (xsinx)
Differentiate both sides with respect to x,
1/y dy/dx = ln3 (sinx + xcosx)
dy/dx = ln3 y(sinx + xcosx)
lny = ln3^(xsinx)
lny = xsinx(ln3) = ln3 (xsinx)
Differentiate both sides with respect to x,
1/y dy/dx = ln3 (sinx + xcosx)
dy/dx = ln3 y(sinx + xcosx)
