5 Trig functions

Question

Sec theta =7/6, sin theta<0. Find the 5 th functions

Answer 1

Draw a right triangle and mark the hypotenuse 7 and one leg 6.

The other leg is square root of 13 (Pythagorean theorem).

Since sin theta is less than 0 but cos theta is positive.

Theta will be in quadrant 4.

You should now be be able to determine the other 5 functions.
