I am writing a script to find the cosine of a value using the Taylor Series, using a while loop.
x = input('Angle in Radians:');d=cos(x);f=1;difference = d - f;difference = abs(difference);threshold = .0001;n = 0;while difference > threshold n = n + 1; f = ((-1)^n)*((x^(2*n))/(factorial(2*n))); difference = d - f; difference = abs(difference); endwhilefprintf('The cosine of %f is %0.3f\n', x, f)
The main issue I am having is the f value is spitting out a NaN. All I could think of was that my equation was somehow dividing by zero but I cannot figure out where. My experience with Matlab is very limited, so if I missed something, it would be very appreciated if someone could point it out.
