Question

Can someone please help me solve "Let theta be an angle in quadrant 3 such that sec theta = -4. Find exact values of cot theta and sin theta

Answer 1

draw a triangle
label the hypotenuse 4 and the "adjacent" side 1 to make the secant 4

Answer 2

find the length of side \(b\) via pythagoras
then you can take any trig ratio you like, just remember you are in quadrant III
