WebOther Functions (Cotangent, Secant, Cosecant) Similar to Sine, Cosine and Tangent, there are three other trigonometric functions which are made by dividing one side by another: Cosecant Function: csc (θ) = Hypotenuse / Opposite. Secant Function: sec (θ) = Hypotenuse / Adjacent. Cotangent Function: cot (θ) = Adjacent / Opposite. WebThe work formula includes the cosine of the angle between the force and distance for this reason. If the force and movement are in the same direction, than the angle is equal to 0 radians (or 0°). The cosine of zero is: cos0 = 1. The units of work are Joules (J), where 1 J = 1 N∙m = 1 kg∙m 2 /s 2 .
