He did the Taylor Series. So we did the 0th,1st,2nd,3rd taylor series and found the value to be 49. But he then decided to plug a value into check that 49 was correct. I understand if we plug 2 into the original equation we get 49. But why did you decide to plug 2 into the equation.
That's what the teacher wanted us to see that the number of the polynomial would be how many derivatives we would have to take to find the Taylor Series for that polynomial. He then picked some value in order to show that 49 was an answer. I am trying to figure how he decided to plug a certain...
Homework Statement
Use zero- through third-order Taylor series expansion
f(x) = 6x3 − 3x2 + 4x + 5
Using x0=1 and h =1.
Once I found that the Taylor Series value is 49. I want to be able to check the value. On the board our teacher plugged in a value into the equation to show that the answer...

I am trying to derive the electric field for a charge volume of a solid cone.
k = constant
pi-y = From Area of pix^2
p - rho
dy - because the cone is around the y axis
b - total length of cone
a - distance above cone
Sorry I forgot to add all the question. Find the electric field at a distance 'a' from the end of a solid cone uniform charge volume. Derive the equation. I just am trying to find the integral i can derive the equation from there.
So the picture is a solid cone around the y axis. With the...
