Question

Java expression for z= sin x/ cos x - 1

Answer 1

Explanation:

include <iostream>

#include <math.h>

using namespace std;

// Function for calculating sin value

void cal_sin(float n)

{

float accuracy = 0.0001, denominator, sinx, sinval;

// Converting degrees to radian

n = n * (3.142 / 180.0);

float x1 = n;

// maps the sum along the series

sinx = n;

// holds the actual value of sin(n)

sinval = sin(n);

int i = 1;

do

{

denominator = 2 * i * (2 * i + 1);

x1 = -x1 * n * n / denominator;

sinx = sinx + x1;

i = i + 1;

} while (accuracy <= fabs(sinval - sinx));

cout << sinx;

}

// Main function

int main()

{

float n = 90;

cal_sin(n);

return 0;

}
