What are the reciprocal trigonometric functions?
In this post, we define the reciprocal trigonometric functions, y = cosec(x), y = sec(x) and y = cot(x) , as a part of the Prelim Maths Advanced course under the topic Trigonometric Functions and sub-part Trigonometric 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
The following video covers all basic trigonometric ratios and their respective reciprocals, to understand where they come from.
