The user should input the value of x and a formatted print statement should be used to display the result. Use a while loop to complete this problem. Note: error I(cos 2x)actual - (cos 2x)estimatel. See below for an example. Enter a value of x: 5 16 terms are needed to meet the tolerance

MATLAB CODE---------------------------

x=input('Enter value of x');

x1=(x*pi)/180;

COS2x_Actual=cosd(2*x)

n=0;

Error=1;

COS2X_estimated=0;

while (Error>0.0001)

COS2X_estimated =COS2X_estimated +(((-1)^(n)*((2*x1)^(2*n)))/factorial(2*n))

Error = abs(COS2x_Actual-COS2X_estimated)

n=n+1;

end

fprintf('\n\n%d terms are needed to meet the tolerance',n)

OUTPUT----------------TEST---------------------OF-----------CODE

```Enter value of x> 45
COS2x_Actual = 0
COS2X_estimated =  1
Error =  1
COS2X_estimated = -0.23370
