1. The problem statement, all variables and given/known data Find the limit: lim (1-cos2x)/(xsinx) x->0 2. Relevant equations Identities 3. The attempt at a solution I've done this over and over and over again! The answer is supposed to be 0 but I keep getting 2 ): lim (1-cos2x)/(xsinx) x->0 lim (1-1+2sin2x)/(xsinx) x->0 lim (2sin2x)/(xsinx) x->0 lim (2sinx)/x x->0 = 2*1 = 2 Any help is appreciated!! Thank you!
