Power of x

		c = 0
		x = 1
		xn = n x(n-1)

Exponential / Logarithmic

		ex = ex
		bx = bx ln(b)
		ln(x) = 1 / x
		logb(x) = 1 / x ln(b)

Trigonometric

		sin(x) = cos(x)
		cos(x) = -sin(x)
		csc(x) = -csc(x) cot(x)
		sec(x) = sec(x) tan(x)
		tan(x) = sec2(x)
		cot(x) = -csc2(x)

Inverse Trigonometric

		arcsin(x)= 1 / (1 - x 2)
		arccos(x)= - 1 / (1 - x 2)
		arctan(x)= 1 / (1 + x 2)
		arccot(x)= - 1 / (1 + x 2)
		arccsc(x)= - 1 / |x|(x 2 - 1)
		arcsec(x)= 1 / |x|(x 2 - 1)

Hyperbolic

		sinh(x) = cosh(x)
		cosh(x) = sinh(x)
		tanh(x) = 1 - tanh2(x)
		csch(x) = - coth(x) csch(x)
		sech(x) = - tanh(x) sech(x)
		coth(x) = 1 - coth2(x)
