2.  Inverse trigonometry functions are used by people in many different professions.  One of the most common uses for inverse trigonometry functions is in carpentry.

3.  Suppose you want make sure that the end of a piece of wood molding is cut at a 45 degree angle.  How would you check to make sure?

4.  You can measure the side lengths at the end of the molding and use an inverse trigonometric function to determine the angle of the cut.

5. θ 1 in. A good cut

6.  Another area where inverse trigonometric functions can come in helpful is mountain climbing, where you might be interested in determining the elevation of a path on a mountain.

7.  This can be useful information for determining which path might be best to take so that you do not overexert yourself on the climb.

8.  Suppose you want to climb up a path that ends 200 feet above your current location and is 400 feet horizontally away from you.  However, you do not want to climb up an elevation greater than 40 degrees, should you make the climb?

9.  You can model this problem using a right triangle and inverse trigonometric functions.

10. 200 ft. 400 ft. θ You can make the climb.
