To evaluate the limits of trigonometric functions, we shall make use of the following. In the study of calculus, we are interested in what happens to the value of a function as the independent variable gets very close to a particular value. It is defined as the limiting value of the ratio of the change increment in the function corresponding to a small change increment in the independent variable argument as the later tends to zero.
