Consider the following function. x 6 dx 1 + x2 (a) Determine an appropriate trigonometric substitution. O Use x = sin(0), where - _ 0<_ since the integrand contains expression v x2. o use x="tan(0)," where _ it or n apply substitution to transform integral into a trigonometric integral. do not evaluate x6 dx="de" x2consider following function. x3 . x2 determine an appropriate substitution. sin h s x2- iii:- tan e sec l r: y fdxi>69 Evaluate the integral using the indicated trigonometric substitution.
