Derivative of sin x Lernen beginnen		cos x
Derivative of cos x Lernen beginnen		- sin x
Derivative of tan x Lernen beginnen		1/((cos x)^2)
Derivative of e^x Lernen beginnen		e^x
Derivative of ln x Lernen beginnen		1/x
Product Rule Lernen beginnen		y = uv -> dy/dx = u(dv/dx) + v(du/dx)
Chain rule Lernen beginnen		y = g(u), u=f(x) -> dy/dx = dy/du * du/dx
x^(-1/2) equals to: Lernen beginnen		1/(x^(1/2))
