and it is more direct. Thanks.

The hypothesized value is the value that is hypothesized: that is, the value that is supposed for the sake of comparison. The null hypothesis here...

ZM=Zach's Money (ZM-0.40ZM)=after store A (after store A)-(after store A)0.25=after store B ............and so on

This question is a mess. Do you mean \text {Given } \displaystyle n \in \mathbb Z^+, \ x > 1, \text { and } s_n(x) = \sum_{j=1}^n...

Hi Erwin1998, welcome to the forum. It's been a while since I've had to think about bending moment (Introductory Mechanics, basically). But having...

Rule #1 - If you don't know what it is, give it a name! "How much money did Zack start with?" I don't know. That's the point of the problem...

In the limit, you can also use older ideas. 1) 1/x + 4/x^2 + 9/x^3 + 16/x^4... = S 2) 1 + 4/x + 9/x^2 + 16/x^3 .. = Sx Subtracting 2) from 1)...

Take it step by step. Suppose he started with $100. How much did he spend at store A? How much was left? Then continue. Then you might think about...

It isn't clear exactly what your teacher is asking you to do, and what you did. There are many ways to prove any identity. My impression is that...

I think you confused us by not saying what you were told to take the derivative of! You seemed to be mentioning the simpler sum in passing, as a...

Hello, I was wondering if someone could explain to me how I should interpret the following 'To ensure the existence of a unique closed-form...

You could, at the very least, have put "/" to indicate fractions and derivatives: \left(1/r\right)\partial u/\partial r+ \partial^2 u/\partial^2r+...

By "next question" I meant (c).

Oops. Thank you for pointing out this error. Yes, you are right. The second question is easier than the first one, so this one should be the...

No 2* here

In my opinion, it's a bit of a silly way to pose the question. Rather than consider cos (theta), consider sin (theta) in triangle ANP. That is...

Sorry, but I have finally worked it out, so I do not need help any more. My working is as follows: The triangles ANP and AMO are actually...

yes i was able to solve it like this. thanks !

no sorry, we are not allowed to use logs but thanks

I have calculated that the minimum bending moment is 105 kn / m. (beam L = 10.5 m) And that the maximum bending moment is 115 kn / m. (beam L = 11.5...
