    5-12-13 right triangle in the 4th quadrant. Draw it; label it and read the function values from the triangle. Short leg 5 is on the horizontal axis. Sine = LEG/HYP So 13² – 12² = 169 – 144 = 25 = 5² so the third leg is 5. The negative sign tells you it is in the 4th quadrant tan θ = –12/5 and cos θ = 5/13 and cot θ –5/12
