Math 221 C. G´omez Summer 2008 D. Milovich The Last Page of Exam 1 These are the formulas and constants that you’ll be given on this exam. You don’t need to worry about memorizing anything on this list. sin 2 u = 2 sin u cos u cos 2 u = cos 2 u - sin 2 u = 1 - 2 sin 2 u = 2 cos 2 u - 1 sin 2 u = 1 - cos 2 u 2 cos 2 u = 1+cos 2 u 2 cos( A + B ) = cos A cos B - sin A sin B sin( A + B ) = sin
