Question

I want to create a Matlab function of the maclaurin series of cos(x), which depends on x and tol, and plot the function for -L_x<=x<=L_x where L_x is a user specified input.

Answer 1

p=input('Enter the value of Lx');
x=-p:0.1:p;
y=1 - (x.^2/factorial(2)) + (x.^4/factorial(4)) - (x.^6/factorial(6)) + (x.^8/ factorial(8))- (x.^10/factorial(10)) + (x.^12/factorial(12)) - (x.^14/factorial(14)) + (x.^16/ factorial(16));

plot(x,y)
