Problem: Given a real number y   [0,1], find the value of x, in radians, such that sin(x) = y, without using any trigonometric-inverse function. The value x should lie within the interval [0, pi(3.14) /2]. Write an iterative program that prints the value of x. Do NOT use a brute-force search at all.

Constraints

0 <= y <= 1

0 <= x <=  pi (3.14) /2

Student submission:
#include<simplecpp>
main_program{
float y;
cin>>y;

float x;
x=arcsine(y);
float ans=(PI/180)*x;
      
     cout<<fixed;
     cout.precision(3);
     cout<<ans;
