Algebra II EXPERT will help you survive & prosper

csc t = 3 means sin t = 1/3. In Qd II sines are positive and cosines are negative. Use Pythagorean identity to calculate cosine, based on this remark. Then find tan t, leading to cot t. Etc....

HINT 1/9 + 8/9 =1 SO cos t = -√8 / 3 and you can simplify square root of 8...
