...limit as n-->infinity exists? Prove that if a sequence, a_n, is bounded and monotonic, then the limit as n approaches infinity exists. Thank you.

If you have taken a Pre-calculus course, were there any challenging topics in the course? Are there any particular types of problems that were hard? Thanks.

(1 - sin(x)^2) / (sin(x) - csc(x)) = cos(x)^2 / (sin(x) - csc(x)) = cos(x)^2 / ((sin(x)^2 / sin(x)) - csc(x)) = cos(x)^2 / ((sin(x)^2 / sin(x)) - (1 / sin(x))) = cos(x)^2 / ((sin(x)^2 - 1) / sin(x)) = cos(x)^2 / (-(1 - sin(x)^2) / sin(x)) = cos(x)^2 / (-cos(x)^2 / sin(x)) = cos(x)^2 * (sin(x) /...
