Websecond quadrant. The angle ω = 90 + θ ω = 90 + θ is shown in the figure as point P. The similar triangle with angle theta is given by Q(x,y) Q ( x, y) in 1st quadrant. Note: Given Q(x,y) Q ( x, y), the coordinate of P P is (P x,P y) ( P x, P y): P x = − y P x = - y and P y = x P y = x. tan(90 + θ) = −x y = − cotθ tan ( 90 + θ ...
