Cos Theta is one of the six trigonometric functions. It is defined by the ratio of the adjacent side to the hypotenuse of the triangle where theta is an acute angle.
In addition, Cosine forms part of the SOHCAHTOA Formula which will help you find all six trigonometric functions (Sine, Cosine, Tangent, Vertical Angle/Cosecant, Oblique Angle/Secant, and Cotangent) from one angle. This makes Cos Theta a valuable tool when working with other Trigonometry Formu...
