How to plot this on a graph

how do u plot this between 0 and 2

syms n x

F = symsum(1/factorial(n),n,1,5)

There is no 'x' in your expression inside symsum(). I guess you are tyring to plot taylor series of exp(x). Try this

syms n x
F = symsum(x^n/factorial(n),n,0,5);
fplot(F, [0 2])

[DARREN O BRIEN]

its a power series which is close to the taylor but still a little different but i was wrong its (n+1)(n+1)-(n-2)/n!

so if u can show how to plot that i would be gratefull

[Ameer Hamza]

Where is 'x' in your series?

[Ameer Hamza]

Can you show the mathematical form of your equations?

[DARREN O BRIEN]

i was right the first time its 1/n! but the maths behind is in the picture its too long too write

[Ameer Hamza]

If you just want to plot 1/n! then you will just get a straight line becuase there is no dependency on 'x'

syms n x
F = symsum(1/factorial(n),n,0,5);
fplot(F, [0 2])

[DARREN O BRIEN]

if u put the numbers in 1, 1/2,1/6,1/24,1/120, 1/720. thats obviously not a straight line

[Ameer Hamza]

But the original question had a reference to symsum() and x range from [0 2], so that was confusing. If you just want to plot 1/n! then you can do it like this

n = 1:5;
y = 1./factorial(n);
plot(n, y)

[DARREN O BRIEN]

sorry for the confusion but in the question we are given its plot the corresponding polynomial over the range 0 ≤ x ≤ 2

[Ameer Hamza]

But how do you define the polynomial from the series of 1/n!. If you look at my original answer. It does create a polynomial.
