### Re: "University Website" discussion (#773)

As a recent high school graduate, and newly enrolled university student, I can definitely say, "Randal, get out of my head!" It took me forever to find course descriptions!

### Re: "Creepy" Discussion

I'd like to address all the lonely guys and girls out there: fuck your low self-esteem, fuck your fear of rejection, fuck your preconceptions of gender roles; if you have feelings for somebody, it is your responsibility to be forward with those feelings. I registered to say this: I've been waffling...

### Re: Logs, Radians and Trig Functions

we turn it into a quadratic equation: ln(5) x^2 + ln(2) x + ln(5)-ln(7) = 0 we use the quadratic equation: x = set of: - ln(2) +/- sqrt( ln(2)^2 - 4 ln(5)^2 - 4 ln(7)ln(5) ) ------------------------------------------------------------ 2 ln(5) I see this is using the quadratic formula of: (-b +/- (s...

### Re: Logs, Radians and Trig Functions

So lets say you have y=3^x. What is x when y is 7? You take the base 3 log of both sides and get x=log3(7)... So log3(7)=ln(7)/ln(3). You evaluate the ln (or log base 10) on your calculator. Okay, sorry. How do I change the base from 10 to 7 on my calculator? As for radians, the radian is an arc on...

Anyway, do you know what an exponential (ie, 10^2, e^3/2, e^x) is?

Yeah, I know what exponential are. I get that log(base10)100 = 2 etc. but I don't know how to solve exponential functions with it.

### Re: Logs, Radians and Trig Functions

Didnt you do logs and trig in precalc/geometry? At my school, we have "Math 12" and "Calculus 12." It is 'preferred' that you complete Math 12 before taking Calculus, as it covers Logs and Trig functions, but myself and a chunk of my peers were stupidly ambitious and decided to ...

### Logs, Radians and Trig Functions

Well, essentially, it is very preferred that I know how to use Logarithms, Radians and Trigonometric Functions in two days for my high school calculus test, but this is somewhat difficult as I haven't learned any of this yet in my other math course. :shock: Any tips or especially important notes to ...

### Calculus Cheque

http://www.motivatedphotos.com/?id=8060

I noticed this motivational poster on a forum, and further observed Mr. Munroe's name in the corner.

Does anyone know if he actually sent this cheque into Verizon Communications? If so, I would like to know their response.
