Differentiate y = 7(x)^2 + cos(x)sin(x)


Let w, z be complex numbers. Show that |wz|=|w||z|, and using the fact that x=|x|e^{arg(x)i}, show further that arg(wz)=arg(w)+arg(z) where |.| is the absolute value and arg(.) is the angle (in polar coordinates). Hence, find all solutions to x^n=1 .


∫(1 + 3√x + 5x)dx


Let f(x) = 2x^3 + x^2 - 5x + c. Given that f(1) = 0 find the values of c.
