Use the pythagorean identity to simplify cot^2x/1+cscx.
cot^2x/1+cscx=csc^2x-1/1+cscx factor (cscx+1)(cscx-1)/1+cscx divide which would cancel out the (cscx+1) leave you with cscx-1
What does 10+2*3=?
You have to remember your order of operations and then we can work through this problem. First, you do multiplication and 2*3=6. Then, you would had 10, which equals 16.
What is the Intermediate Value Theorem?
The intermediate value theorem states that a function is continuous. It also states that in the function you will have a number above and below your number because it is continuous.
