1. The problem statement, all variables and given/known data lim as x goes to 0 of [x*csc(2x)] / cos(5x) 3. The attempt at a solution The book solution says the answer is 1/2. I keep getting zero as an answer because of the x in the numerator and am unsure of how else to go about the problem. I'm pretty sure I'm supposed to use the limit as x goes to 0 of sinx / x, but even when I get to that point the limit of x as x goes to 0 always gives me an answer of zero. What am I doing wrong? Thanks!
