Table 12.5 provides you with a summary of how to generate tangent and cotangent values. To generate a tangent value, you divide sin θ by cos θ. To generate a secant value, you use the reciprocal of cos θ. A variety of approaches to arriving at the different values of the trigonometric functions exist. The approach given in Table 12.5 proves one of the easiest to follow.
|If the value of the of cos θ in this function is 0, then the value of the tangent is undefined. When you plot tangent values on a Cartesian plane, the resulting curve rises indefinitely ...|
