tan theta = 2 opposite area = 2 adjoining area = a million hypotenuse = sqrt(2^2 + a million^2) = sqrt 5 because sin theta < 0, theta is interior the third Q. sin theta = -2/sqrt5 = -2sqrt5/5 cos theta = -a million/sqrt5 = -sqrt5/5 tan theta = 2 cot theta = a million/2 sec theta = -sqrt 5/2 csc theta = -sqrt 5
