Question

How to use asin() function to get the arc sine value of N in C++

Answer 1

#include <iostream>
#include <cmath>
#include <cfloat>      

using namespace std;

int main()
{
	cout << "asin(1) = " << asin(1) << endl;
	cout << "asin(0) = " << asin(0) << endl;
	cout << "asin(10) = " << asin(10) << endl;
	cout << "asin(0.5) = " << asin(0.5) << endl;;
	cout << "asin(DBL_MAX) = " << asin(DBL_MAX) << endl;
	cout << "asin(INFINITY) = " << asin(INFINITY) << endl;

	return 0;
}

// "NAN" is "not-a-number" - applies to float and double

/*
run:

asin(1) = 1.5708
asin(0) = 0
asin(10) = -nan(ind)
asin(0.5) = 0.523599
asin(DBL_MAX) = -nan(ind)
asin(INFINITY) = -nan(ind)
