Program to find the Eccentricity of a Hyperbola
• Last Updated : 13 May, 2021

Given two integers A and B, representing the length of the semi-major and semi-minor axis of a Hyperbola of the equation (X2 / A2) – (Y2 / B2) = 1, the task is to calculate the eccentricity of the given hyperbola.

Examples:

Input: A = 3, B = 2
Output: 1.20185
Explanation:
The eccentricity of the given hyperbola is 1.20185.

Input: A = 6, B = 3
Output: 1.11803

Approach: The given problem can be solved by using the formula to find the eccentricity of an ellipse. • The length of the semi-major axis is A.
• The length of the semi-minor axis is B.
• Therefore, the eccentricity of the ellipse is given by where A > B

Therefore, the idea is to print the value of as the eccentricity of the ellipse.

Below is the implementation of the above approach:

## C++

 // C++ program for the above approach #include using namespace std; // Function to find the eccentricity// of a hyperboladouble eccHyperbola(double A, double B){    // Stores the squared ratio    // of major axis to minor axis    double r = (double)B * B / A * A;     // Increment r by 1    r += 1;     // Return the square root of r    return sqrt(r);} // Driver Codeint main(){    double A = 3.0, B = 2.0;    cout << eccHyperbola(A, B);     return 0;}

## Java

 // Java program for the above approachimport java.util.*; class GFG{ // Function to find the eccentricity// of a hyperbolastatic double eccHyperbola(double A, double B){         // Stores the squared ratio    // of major axis to minor axis    double r = (double)B * B / A * A;     // Increment r by 1    r += 1;     // Return the square root of r    return Math.sqrt(r);} // Driver Codepublic static void main(String[] args){    double A = 3.0, B = 2.0;         System.out.print(eccHyperbola(A, B));}} // This code is contributed by Amit Katiyar

## Python3

 # Python3 program for the above approachimport math # Function to find the eccentricity# of a hyperbola  def eccHyperbola(A, B):     # Stores the squared ratio    # of major axis to minor axis    r = B * B / A * A     # Increment r by 1    r += 1     # Return the square root of r    return math.sqrt(r)  # Driver Codeif __name__ == "__main__":     A = 3.0    B = 2.0    print(eccHyperbola(A, B))     # This code is contributed by ukasp

## C#

 // C# program for the above approachusing System; class GFG{ // Function to find the eccentricity// of a hyperbolastatic double eccHyperbola(double A, double B){         // Stores the squared ratio    // of major axis to minor axis    double r = (double)B * B / A * A;     // Increment r by 1    r += 1;     // Return the square root of r    return Math.Sqrt(r);} // Driver Codepublic static void Main(String[] args){    double A = 3.0, B = 2.0;         Console.Write(eccHyperbola(A, B));}} // This code is contributed by Princi Singh
