Unformatted text preview: Math 172 EXAM 2 Review problems Remember to bring photo ID to the test. This is not intended to be a practice version of the test. These problems are intended to help you practice applying all the concepts and techniques weve learned so far. The actual exam may have different types of questions on it. Heres what youll be given on this exam: Identities: sin 2 ( x ) + cos 2 ( x ) = 1 sin 2 ( x ) = 1 2 [1 cos(2 x )] cos 2 ( x ) = 1 2 [1 + cos(2 x )] Taylor series formula: f ( x ) = summationdisplay n =0 f ( n ) ( a ) n ! ( x a ) n Known Maclaurin series: 1 1 x = summationdisplay n =0 x n = 1 + x + x 2 + x 3 + . . . e x = summationdisplay n =0 x n n ! = 1 + x 1! + x 2 2! + x 3 3! + . . . sin( x ) = summationdisplay n =0 ( 1) n x 2 n +1 (2 n + 1)! = x x 3 3! + x 5 5! x 7 7! + . . . cos( x ) = summationdisplay n =0 ( 1) n x 2 n (2 n )! = 1 x 2 2! + x 4 4! x 6 6!...
