## Hyperbolic Functions

In this post we define Hyperbolic  Functions and also discuss their domains and ranges. The  hyperbolic Functions have same properties that resembles to those of trigonometric functions. Functions                       Formulas y = Sinh x y = Cosh x  , Range=[1,+) y = Tanh x     y = Coseh x   y = Sech x    y = …

## Trigonometric Functions

Trigonometric Functions We denote and define trigonometric functions as follows. Function Domain Range Y=Sinx R -1  ≤ Y ≤  1 Y=Cosx R -1 ≤  Y ≤  1 Y=Tanx {x: x ∈ R and x ≠(2n+1) } R Y=Cotx {x: x ∈ R and x ≠n } R Y=Secx {x: x∈ R and x≠(2n+1) } y ≥1,  y ≤  -1 Y=Cosecx …

## GRAPH OF ALGEBRIC FUNCTION

In this post we highlight the point that which graph is function and not a function.  If a vertical line intersects a graph in one point, it is the graph of a function. If a vertical line intersects a graph in more than one point, it is not the graph of a function.   READ MORE DEFINITIONS CLICK HERE

## INVERSE FUNCTION

In this post we define inverse function and also provide an example to clear the concept of it. The inverse function of f denoted by f-1 is a function from Y onto X and is defined by x= f–1(y)  for all x in y if and only if as y=f(x) , for all x The set X of all possible input values is …
