hi thank you for your help: i have a question that deals with finding the direction and magnitude of the net magnetic force on a loop that is next to a wire (the loop is in the wire's magnetic field) how do i set up a question like this? do i have to integrate since the fa...

hi im trying to do a problem that involves multiple battereis, one capacitor,and multiple resistors, and im told that the circuit has been connected for a very long time... i found the current passing thru each battery using kirchoffs rules, but now i have to find the capacit...

hi i startted the problem below by writing a sigma notation of sigma[(2^(n+1))/((n+1)!)] QUESTION: how do i find the sum of 2+(4/2!)+(8/3!)+(16/4!)+... was my attempt wrong, or how do i go from here? thank you!

**calculus repost, please assist pleassssssse**

Hi Trying to work with confusing Taylor series....any assistance would be much appreciated!! How can I use T(x)=5-9((x-2)^2)-3((x-2)^3) to approximate the f(0) ???? I realize that Taylor series f(x)=f(a)+f'(a)(x-a)+f''(a)((x-a)^2)etc... but the above T(x) is cente...

Hello, I am learning about Taylor series in school, but they are quite confusing.. Can you please explain how I should do this problem? Thank you very much! What is the Taylor polynomial of order 5 approximation to sin(1.5) ? I know the series of sinx = x - ((x^3)/(3!)) + ((x^...

**Math CONTINUATION OF QUESTION FROM bobpursley**

Thank you for answering the question before bobpursley, I understand how you did the deriv of inside, outside, but how do I now do the second derivative since you have the extra -18x^2 in the numerator?? Thank you very much! (I suppose I have to brush up on my derivatives) Pos...

What is the first and second derivative of 3/(1+2(x^3)) ? im tempted to do the quotient rule, but this looks weird to me...any advice would be greatly appreciated!!

Thankyou very much! I'm having trouble with this question about taylor series. how would i go about doing the following questoin? thank you! find the maclaurin series for the function sin(x)-x+((x^3)/3!) how do i do this? thanks aagain

**Calculus**

Hi~ Thank you for your help! I was trying to work on a problem about Taylor series, but i don't think im approaching the problem the right way. I have to find the fifth order Taylor polynomial and Taylor series for the function f(x) at x = 0. f(x) = 1/(x+2) I tried to just...

**math quick question**

Hi! Thank you for your help~~ What is the absolute value of (3x - 6)^2 ? (i am trying to use this to find the radius of convergence of a power series by the way)..

Hi thanks for your help The answer to this problem is supposed to be 1870 [N (m^2)/ c] but im getting 1497 instead. If you could help me get the right answer that would be super. The problem says that there is a pyramid with a square base whose side lengths are 6 m and the hei...
