Given: Trigonometric expressions 1) tan theta = 2.6 tan(-theta) = - tan theta = - 2.6 2) cos theta = - 0.65 cos(-theta) = cos theta = - 0.65 3)csc(-theta) = -(3)/(2) -csc(theta) = -(3)/(2) csc theta = (3)/(2) 4) sec(-theta) = (6)/(5) (1)/(cos (-theta) = (6)/(5) (1) cos theta = (6)/(5) cos theta = (6)/(5) 5)cos(-theta) = - (3)/(5) & sin(-theta) = (4)/(5) cos theta = (3)/(5) -sin theta = (4)/(5) sin theta = - (4)/(5) tan theta = (sin theta)/(cos theta) = ((-4)/(5))/((3)/(5)) = (-4)/(3) 6) cos theta = - (12)/(13) & sin v = (5)/(13) cot(-theta) = (cos (-theta))/(sin (- theta)) = (cos theta)/(-sin theta) = (-(12)/(13))/(-((5)/(13))) = (-12)/(-5) = (12)/(5)
