Graphing Cosec, Sec and Cot is a part of the VCE Specialist Maths topic Functions and Graphs, and subtopic Reciprocal Trigonometric Functions. In this post, we look at the graphs of reciprocal circular functions of cosecant, secant and cotangent. We also look at simple transformations of these functions.
The reciprocal trigonometric functions are:
- cosec(A) = \frac{1}{sin(A)}, sin(A) \neq 0
- sec(A) = \frac{1}{cos(A)}, cos(A) \neq 0
- cot(A) = \frac{cos(A)}{sin(A)}, sin(A) \neq 0
What is a Reciprocal Function?
This video covers all basic trigonometric ratios and their respective reciprocals, to understand where they come from.
