taylor function is not working

i have matlab 2014b and when i came to get taylor expansion of some functions by writting taylor(sin(x),5,0) the matlab gives error knowing that all other functions works properly thanks in advance

Answer 1

If you want to do a 5th-order Taylor series around an expansion point of 0 in R2014b, this works:

syms x
TSsin5 = taylor(sin(x), x, 'ExpansionPoint',0, 'Order',5)

and produces:

TSsin5 =

- x^3/6 + x

Answer 2

[James Tursa]

It is complaining about the 5 and 0 arguments, which don't match the expected syntax for calling the taylor function. Is something like this what you are trying to do?

>> syms x
>> taylor(sin(x))
ans =
x^5/120 - x^3/6 + x
>> taylor(sin(x),'Order',10)
ans =
x^9/362880 - x^7/5040 + x^5/120 - x^3/6 + x
