Thread: Homework Help with a Simple Program (I'm new to C++)

Hello, I have a program that I am trying to write. I want it to ask the user for an angle in radians, then the desired accuracy the user wants to use, and then the answer. The angle should appear as the x in the answer sin(x) = # (Demonstrated below and a I especially need help with this part).
The program uses the Taylor series for sinx (x - x^3/3! + x^5/5! - x^7/7! + ...) to solve. The end product should look like this:

Enter angle in radians
1.57
Enter the desired accuracy
0.0000001
sin(1.57) = 1

Here is what I have so far:

Code:

#include <iostream>
#include <cmath>
using namespace std;

int main()
{
  float sinx, x, acc, term;
  int n = 1;

  cout << "Enter angle in radians " << endl;
  cin >> x; 
  cout << "Enter the desired accuracy " << endl;
  cin >> acc
  
  sinx = 0;
  term = x;

  while (abs(term) >= acc)
  {
    sinx = sinx + term;
    n++;
    term = -term*x*x/((2*n-2)*(2*n-1));
  }

  cout << "sin(x) = " << sinx << endl;

  return 0;
}

I keep getting errors and am still new to C++ so I'm not sure what the mean:
sinx.cpp: In function 'int main()':
sinx.cpp:15: error: expected ';' before 'sinx'


Thanks for any advice!!
