Can complex number be used in real world application? That seems like an argument that high

Hi class,
This week's problem looks really interesting to me. I have never used this method and I must say
that it is not too easy but if we follow the steps for Newton's Method, I think we will be in pretty good
shape.
The question gave us two functions,

It has been exactly one week since I learned about Newton's Method and even though I am
getting a bit familiar with the formula, I am still learning more about it, especially from watching

Find points of inflection and discuss concavity for f(x)=x(x4)3+k.
Each student should post their new equation for f(x) as the first line of their post.

etc.

Hi class,
I was a bit confused when I first read this week's problem description. However, I think there is
something missing to it because I think as we determine k's value, the value of the point (1,3) will
change as well. Yvalue of (1,3) will be added
Hi class,
Memorizing formulas is not too bad but if there are so many formulas, it can become brutal. I
remember in high school, I have to memorize formulas before the exam because the teacher did not
allow us to have it on the paper or on the board. As f

We started this week by applying the power rule to derivatives. This makes calculating the derivative
easier without having to using the limit definition. We looked a proof of this power rule. We looked at
