Phi just means the angle... Like theta or so.

I think I get what you mean... Phi is also the golden ratio.

Yeah, I thought it might be some other constant...because apparently there are a bunch of them out there represented by Greek letters that I don't know about. :lol

I HAS A MATHS QUESTION


but it's for a class to take


what do you guys think about a class called Survey of Calculus? I just need a math credit and I'm not majoring in anything math related, but i don't know anything about calculus and this is pretty much the only class available.

Survey usually means ree-ree. I'd take it.

What's the course description say?

Prerequisite: Algrebra (which I have taken)
Rates of change, derivatives, and integration with applications to business are studied.

Sounds like it's basically introductory calculus...

...which means it could be really easy or it could be a total bitch - it completely depends on the teacher.

Given you only have algebra background, it shouldn't be too bad.  "Real" Calculus would require trigonometry and pre-calculus, so you should be ok.

This. I took AP Calc as a Junior, which should've been easy, but the teacher also happened to be the bitchy track team coach (Our school is in a rural town filled with hicks, so there's not too much need for book learnin).

She went over shit in the most complex way possible, and I ended up as one of two students, in a class of about sixteen, to pass the AP exam. Even though it was just simple integrals and derivatives...

Then I took a Dual Enrollment Calc II course at a technical college, and it was the easiest class I had that semester. The teacher really matters when you get up to anything complex.

This. It sounds like it isn't a rigorous course in calculus, so it should be Calculus Lite.

Yeah, that is a standard Calc 1 class, which you need trig and precalc for.

Although it makes me scratch my head sometimes because people at my college can skip trig and go straight to Calc 1, and when those students get to Calc 2, they get really lost.

So is it pretty much agreed that I should take it? I'm all for putting in the effort for the class, I just didn't want to take something way above my level of knowledge.

You should be fine.  A lot of the introductory calculus concepts are simply an expansion of algebra.  Based on your description, you won't have to do crazy stuff with trigonometry and the unit circle.  I'm not sure how much they'll cover derivatives and integration, but they're just procedures you have to memorize, and if the professor does a good job, you'll understand the concept of what they mean.

What math classes have you taken exactly? Algebra I and II? Geometry? I think you should be fine if it is just a light version of the subject.

I've had the standard college Algebra class (as opposed to the remedial/intermediate/introductory ones) and I was o.k. at it. I was really good at Geometry in high school though.


I'll go for this but hopefully I can get a statistics class or something haha

I have my Calc III final this Thursday. It'll be full of three-dimensional vector calculus and double integral stuff. Loads of fun.

Statistics is cool. it is half dissecting the problem (which isn't too bad) and half actual math to do.


Calc III is fun stuff...I am going through it all again on my own because a bunch students here at the college will be coming to me for some help. :lol

It's cool though, in calculus, you see algebra, geometry and trig come together very nicely. It's beautiful.

I just started my Vector Calculus summer course yesterday.. Hopefully it goes well.
Good luck to you tomorrow!

I'm a chem major in uni, so I have to take several calculus and algebra classes, all of which have been mentioned/alluded to in this thread. However, all of my uni friends are bio majors, and only have to take one calc class, which I recently discovered did not cover anything having to do with trigonometry.
I was stunned. And immensely jealous.

^For real. I've never taken physics in any form(I really should), but it's cool to help the physics students at the college with problems, even if I don't fully understand what is going on.

I'm not looking forward to calc just because of these things. I adore algebra. The shit we are doing now, there is a good 3-4:1 ratio of variables to real numbers. That is when you know everything is right in the math world.
Once you get the basics of calculus down, it becomes a breeze!

I thought double and triple integrals were nice.

It was vector analysis that confused me, but that is more due to my professor being so pressed for time at the end that she didn't really teach it to us. Sucks, because I occasionally get asked about line integrals and I am unsure of what they are at the moment (working toward that section now).

Nah, that's just doing the same process again and again, basically.

Now those I didn't like either.


EDIT: Although, for some reason, integrals and differential equations become very important when analyzing electrical circuits. Since I'm currently taking circuit analysis, I am not amused.

If they stayed only with KCL and KVL I would love it! But on circuit analysis 2 (yeah, another one) they bring Laplace transforms! FML
