My o-chem book says that phosphorus can have more than 4 covalent bonds. Why is this with respect to valence bond theory?

You will learn everything in a high-school calculus class that you would in a college calculus class. That said, I found university calculus to be much, much harder than high-school calculus. I never did homework in high-school, slept through class and got an A in calculus BC. I took college...

Hmm, I don't know if this is correct or not, but have you tried long division?

Homework Statement Determine whether the given vector functions are linearly dependent or independent on the interval (-\infty, \infty) \begin{pmatrix} t \\ 3 \end{pmatrix}, \begin{pmatrix} 4 \\ 1 \end{pmatrix}Homework Equations The Attempt at a Solution I computed the wronskian to be t-12...

No worries! Please don't apologize, I was just curious.

Hmm. A friend is telling me that "The fusion in the sun produces radiation of several types, including beta positive and gamma in huge quantities" Is this just radioactive waste?

I was just wondering if nuclear fusion is considered a radioactive process?

Thanks, I completely mistyped that. 3 should read opened rather than closed. Just to clarify, the answer to #1 should be: I=V/R where I = 55/150?

Thanks, I completely mistyped that. 3 should read opened rather than closed. Just to clarify, the answer to #1 then should look like the following? \frac{V}{R} = I where I is 55/150?

I'm not a big fan of the right-hand rule; it always confuses me. The system I use, which works pretty well for me, is that since you're looking for the cross product, why not just take the determinant? We know that F = q\vec{v}\times\vec{b}. For both problems, we have the particle moving in...

Thanks!

I was playing around with Euler's identity the other day. I came across something that seems contradictory to everything else I know, but I can't really explain it. I started with e^{i\pi} = -1. I rewrote this as ln[-1] = i\pi Multiplying by a constant, we have kln[-1] = ki\pi...

The text Evolutionary Analysis asserts otherwise. In general it states that the selection coefficients are generally (over 70% of the time) less than .02, (http://www.jstor.org/pss/2640707) but that most mutations are slightly deleterious.

My Biology text, Evolutionary Analysis, claims that survival to sexual maturity decreased in C. elegans that originated from a single progenitor and were kept in a benign environment to decrease selective forces. This is cited from a paper by Vassilieva in 2000. My book claims that this...
