Please help with my Calc 2 hw. It's one math problem broken into parts to help us.

1.) Evaluate the integral Using Trigonometric substitution dx * V x 2_ 4 Use the substitution x= asecA and the indentity tande = seca e - 1. a. First, write down your substitutions: X = dx = b. Now plug in your substitutions and integrate with respect to O. C. Finally, express your answer in terms of x instead of O. you must draw the Triangle and label its sides write your final answer here
