symsum gauß, how to calculate sum of series ?

Hello everyone,

so this is what i was working on ,

function y = sin(x,n)

if n<=0 %if y=0/neg. Numer -->y=0

y = 0;

elseif n~= floor(n) %if y= pos.decimal-->y=NaN

y=NaN;

else

%Gauß

syms i x n

symsum (-1)^i*((x^2i+1)/factorial(2i+1)),i;1,n); is symsum the right thing to use here?

end

end

Can somebody help pls ?

There are a few curcial errs in your developed code.

(1) Don't name a function with MATLAB's builtin function names. You have named sin() that is a builtin fcn of MATLAB.

(2) This exercice can be solved more efficiently in terms of computation time using numerical calcs instead of symbolic math application that would be very slow.

okay ty for the feedback, what would you reccomand for point (II)?
