Suppose cot = 3 in the 3rd quadrant.
I know that tan = 1/3 and than both sin and cos are negative, but i can't figure out what the values for them are.
I tried sin = 1/3cos and then
cos^2 + 1/9cos^2 = 1
cos^2 = 8/9
cos = -2sqrt(2)/3 but then i keep getting the wrong answer. Can someone help me find sin and cos please
