Your algebra is correct, you could also arrive there by some analysis. csc(x) as x -\> pi becomes infinitely large. You cannot directly compute sqrt(x), as x -\> pi, since pi is irrational and has no square root. BUT, since csc(x), x -\> pi, becomes huge the closer and closer you get to pi, and since sqrt(x), x-\>pi, is roughly constant. You have a denominator that is increasingly increasing, and a “constant” numerator. Thus it must tend to 0. Hope that helps with the reasoning. --- _[View the full topic](https://forums.speedlife.net/t/hw-help-12th-grade-calc/36371)._
