    Calculating 13th Taylor Coefficient of f(x)=e^(7x) at x=3

    Isn't it the 13th value of n that gives the 13th term?

    Calculating 13th Taylor Coefficient of f(x)=e^(7x) at x=3

    Homework Statement Determine its 13^{th} Taylor coefficient of the Taylor Series generated by f at x = 3. f(x)=e^(7x) Homework Equations I used the fact that the series for e^x was ∑x^n/n! The Attempt at a Solution Using that above, and replacing x with 7x, shouldn't my answer...

    What is the 13th Taylor coefficient of f(x) at x=3?

    I'm still a bit confused. What do you mean by substituing the series into the above?

    What is the 13th Taylor coefficient of f(x) at x=3?

    So how do I find the coefficient? Do I have to take the 11th derivative of xe^x, plug 7 in, divide by 11! ? But then what happens with the (x-7)^11?

    What is the 13th Taylor coefficient of f(x) at x=3?

    Maybe I'm going about the problem wrong? I seem to be getting a lot of them wrong. f(x)=3xe^x. Determine its 11^{th} Taylor coefficient of the Taylor Series generated by f at x = 7. For this, I am getting 3*7^14/13! and that is wrong too

    What is the 13th Taylor coefficient of f(x) at x=3?

    Homework Statement F(x)=7x Determine the 13th taylor coefficient of the taylor series generated by f at x=3 Homework Equations Well, it looks like I just had to take the derivative, but by the time it gets to the 13th derivative, wouldn't the answer just be zero? The Attempt at a...

    "How do I compute the Taylor series for cos(7x^2) at x=0?

    If I had a function asking the same thing as above but the function was 4+15x+x^2sinx, how would I fin a taylor series for this? Would I have to expand out the x^2sinx? What would I do with the 4 and the 15x? I know if I expand out the x^2sinx, I would multiply them to each other, but where...

    "How do I compute the Taylor series for cos(7x^2) at x=0?

    Oh! so, if it asks for a certain polynomial, the power can't be higher than what they're asking for? That P(5) refers to the power, and not the term?
