Calculus 2 Answer and Explain. Thank You!

Evaluate the integral. Show that the substitution x = 7 sin(9) transforms I into f (19, and evaluate I in terms of 9. dx I: /'\\/49)c2 (Use symbolic notation and fractions where needed. Use C for the arbitrary constant. Absorb into C as much as possible.) Evaluate I in terms of x. (Use symbolic notation and fractions where needed. Use C for the arbitrary constant. Absorb into C as much as possible.) I I \\ Question 3 of 6 > Evaluate the integral. Show that the substitution x = W sec(9) transforms I into % f cos(9) dB, and evaluate I in terms of 9. I _ dx Jtzx/Jc2 7 (Use symbolic notation and fractions where needed. Use C for the arbitrary constant. Absorb into C as much as possible.) I Evaluate I in terms of x. (Use symbolic notation and fractions where needed. Use C for the arbitrary constant. Absorb into C as much as possible.) Use the indicated substitution to evaluate the integral. dx, x = 7 sec(9) l [xx/x2 49 (Use symbolic notation and fractions where needed. Use C for the arbitrary constant. Absorb into C as much as possible.) /\\/149d= : /\\ Question 5 of 6 > Attempt 3 V Evaluate using trigonometric substitution. Refer to the table of trigonometric integrals as necessary. (Use symbolic notation and fractions where needed. Use C for the arbitrary constant. Absorb into C as much as possible.) dx f Hz -225 - Z Evaluate the integral using trigonometric substitution. (Use symbolic notation and fractions where needed. Use C for the arbitrary constant. Absorb into C as much as possible.)
