  1. Draw a right triangle and pick one of the acute angles to be , as instructed in the problem.
  2. Rewrite the 15 in the csc equation as a fraction:
    .
  3. Since the ratio for csc is hypotenuse over opposite, make the hypotenuse of the triangle be a 15 (the numerator of 15/1) and make the side opposite to be a 1 (the denominator of 15/1)
  4. Use the Pythagorean Theorem to find the side which is adjacent to . (Hint: It will be a square root.)
  5. Now that you have all three sides, the hypotenuse and the sides which are opposite to and adjacent to , you can now set up the ratios for the other five trig functions.
  6. Some of the ratios from the previous step will have the square root from step 4 in the denominator. Rationalize these fractions by multiplying the numerator and denominator of the fraction by the square root.
