WebThe value of cos 135 degrees can be calculated by constructing an angle of 135° with the x-axis, and then finding the coordinates of the corresponding point (-0.7071, 0.7071) on the unit circle. The value of cos 135° is equal to the x-coordinate (-0.7071). ∴ cos 135° = -0.7071. WebThe reciprocal of sine, cos, and tan are cosecant (csc), secant (sec), and cotangent (cot) respectively. The formula of each of these functions are given as: Sec a = 1/ (cos a) = Hypotenuse/Adjacent = CA/AB Cosec a = 1/ (sin a) = Hypotenuse/Opposite = CA/CB cot a = 1/ (tan a) = Adjacent/Opposite = BA/CB solithor
