  10. TRIGONOMETRIC SUBSTITUTION

  11. TRIGONOMETRIC SUBSTITUTION We can transform the integrand into a function for which trigonometric substitution is appropriate by first completing the square under the root sign

  12. TRIGONOMETRIC SUBSTITUTION

  13. TRIGONOMETRIC SUBSTITUTION In the following table we list trigonometric substitutions that are effective for the given radical expressions because of the specified trigonometric identities.

  20. TRIGONOMETRIC SUBSTITUTION Example Find hyperbolic substitutions can be used in place of trigonometric substitutions and sometimes they lead to simpler answers. But we usually use trigonometric substitutions because trigonometric identities are more familiar than hyperbolic identities.

  21. TRIGONOMETRIC SUBSTITUTION Because the ellipse is symmetric with respect to both axes, the total area is four times the area in the first quadrant
