One of them has the form y = , where k is a real number and x ≠ 0. Unlike the graphs of sine and cosine, secant and cosecant have vertical asymptotes whenever the cosine and sine equal zero, respectively. It is an odd function. Asymptote ; The line the graph approaches, but does not touch ; Horizontal (k) Vertical (h) Parent Function ; 3 Each part of the graph is called a branch. The reciprocal number to x may be denoted simply as 1/x, but also as x-1. Starting off with 1 over x graphs, then moving onto 1 over quadratic, 1 over cubic types of reciprocal graphs.

Th e graphs of reciprocal functions have vertical asymptotes at the zeroes of their primary trigonometric functions.. Learn how to graph the reciprocal function. example. It is a Hyperbola. How to move a function in y-direction? The reciprocal functions of the sine, cosine, and tangent are, respectively, the cosecant, secant, and the cotangent.They are of limited practical use nowadays, given our calculation capabilities, but are still a part of the school curriculum in high schools and universities. A reciprocal function, such as `y = (1)(x)`, creates two curves on the graph in opposite quadrants.There are values on the graph which cannot be found: `x = 0` is a division by zero; and `y = 0` requires `x` to be equal to infinity. Its Domain is the Real Numbers, except 0, because 1/0 is undefined. So why not check out our other tools!
