[π/2, π]
Many problems in this class, start off with a simple drawing of a right triangle. Since this skill is so important, let's practice by drawing a right triangle for each of the following given pieces of information. Put the triangle in the proper quadrant and label all three sides with their lengths. Include negatives where appropriate. Check your solutions by clicking here.
| sin α = 5/6 with α [π/2, π] |
cos β = 2/3 and tan β < 0 |
| tan γ = 23/14 and cos γ < 0 |
sec θ = -29/18 cot θ > 0 |
