Use the fundamental identities to simplify the expression. Use the table feature of a graphing utility to check your result numerically.

Question

9 / cot²(x)+1

Answer: ____

Answer 1

I can't tell from how you've written it, but I'm guessing the entire expression (cot²(x)+1) is the denominator.

Assuming so, using a version of the fundamental trig ID, the expression becomes 9/csc²x = 9sin²x
