How To Find Domain And Range Of A Hyperbolic Function
B use a graphics calculator to sketch the function f x a tanh x with domain x r.
How to find domain and range of a hyperbolic function. How to make a table of values on the ti89. Make a table of values on your graphing calculator see. The hyperbolic functions appear with some frequency in applications and are quite similar in many respects to the trigonometric functions.
2 sin 3x 0. Definition 4 11 1 the hyperbolic cosine is the function cosh x e x e x over2 and the hyperbolic sine is the function sinh x e x e x over 2. So the domain is all real values.
So we will not the above situation at any more. Do the curves ever intersect. Fractions with nonzero numerator cannot equal 0.
This is a bit surprising given our initial definitions. Sin 3x 2. Then plug that answer into the function to find the range.
Range for sin function is between 1 and 1 1 sin 3x 1. To properly notate the range write out the numbers in brackets if they re included in the domain or in parenthesis if they re not included in the domain. Chapter 2 hyperbolic functions 37 activity 5 a superimpose the graphs of y cosh x and y sinh x on the screen of a graphics calculator.
Finding the range of a hyperbolic function. In order to find the domain let us equate the denominator to 0. This is impossible because the minimum value of sin is 1 and maximum value is 1.
