Computing the sine of angle using the built in trigonometric function and The Taylor series approximation

[tce19]

The assignment is about computing the sine of the angle using the built in trigonometric function and computing the sine using the Taylor series approximation.

• Prompt for input angle in units of radians.
• Read input angle in units of radians.
• Compute and output the sine of the input angle using built-in trigonometric functions.
• Compute and output the Taylor series approximation of sin(x) including terms up to order seven (i.e., 7 x ).

***It won't execute the expression that I put*** Please help


#include <iostream>
#include <cmath>

using namespace std;

int main()
{

double angle= 0.0;

double sin= 0.0;

double value;


cout << "Please Enter an Angle in Units of Radians...";
cin>> angle;

value = sin * (angle);


cout << "The sine of angle is ...";
cin >> value;


value = ((angle) - (pow (angle,3) / 6) + (pow (angle,5) / 120) - (pow (angle,7) / 5040));

cout << "The sine of the angle in Taylor Series approximation...";
cin>> value;





return 0;
}

That's pretty close, but a few errors too.

Mainly, you are asking the user for input (cin) when you should be displaying the result (cout).

Also, you don't need this variable: double sin= 0.0;, delete that line.

Then change this line:

value = sin * (angle);  // multiply variable sin by variable angle 

to this:

value = sin(angle); // call the sin() function
