Evaluating trig functions (csc, sec, cot)

What is csc, sec, and cot? The basic three trig. Functions are the typical sin**θ**, cos**θ**, and tan**θ**. However, there are also another three types of trig. Functions, however, these other functions are the opposite of sin**θ**, cos**θ**, and tan**θ**. These new trig functions are known as csc**θ**(cosecant) = sin**θ**, sec**θ** (secant) = cos**θ**, and cot**θ** (cotangent) = tan**θ**. For example, sin**θ**= (opposite / hypotenuse) however, csc**θ**= (hypotenuse / opposite). cos**θ** =(adjacent / hypotenuse) while sec**θ**= (hypotenuse / adjacent). Last but not least there is tan**θ**= (opposite / adjacent) while cot**θ**= (adjacent / opposite). These six trigonomic functions are used only for right triangles. In addition, you cannot divide by zero and so these definitions are only work when the denominators are not zero.
