Final exam information

The following is a list of formulae that will be provided on the final exam should they be required.

Name	Equation
Law of Cosines	$a^2=b^2+c^2-2bc\cos(\theta)$
Trig identities	$\sin^2\theta +\cos^2\theta=1$
	$\sin(A+B) = \sin(A)\cos(B) + \cos(A)\sin(B)$
	$\cos(A+B) = \cos(A)\cos(B) - \sin(A)\sin(B)$
