Use the Double ang formula: ⌠ cosx + 2sinxcosx / sinx dx then somehow he gets to ⌠ sinx/cosx then he gets that to ⌠ 2cosx dx I just need help to get to those 2 steps, I can do the substitution.

I understand pretty well why derivative of sin(x) is cos(x) and of cos(x) is -sin(x). That makes sense, since derivative expresses the "angle of normal", I can see that from graph easily. However, when I try to - analogically, using a graph - find integral of sin(x), I can't seem to make sense of it. Here's my graphs:

[ { (1+t)/ (1+t^2)} +1/ (1+t)] dt. The notations sin −1 (x), cos −1 (x), tan −1 (x), etc., as introduced by John Herschel in 1813, are often used as well in English-language sources —conventions consistent with the notation of an inverse function. Integral sin, cos, sec.

=cosx - 2/3cos^3x + C Use the identity cos(2x) = 1 - 2sin^2x. =int(1 - 2sin^2x)sinxdx Multiply out. =int(sinx - 2sin^3x)dx Separate using int(a + b)dx = intadx + intbdx =int(sinx)dx - int(2sin^3x)dx The antiderivative of sinx is -cosx. Use the property of integrals that int(Cf(x))dx = Cintf(x) where C is a constant. Note that sin^3x can be factored as sin^2x(sinx), which can in turn be written
