Pre-calculus is a transition class from introductions in algebra, geometry, and trigonometry into an introductory understanding of calculus. Most pre-calculus classes spend large amounts of time covering topics required to "do the work" in calculus.
LCKurtz's answer still applies.
I'm a 27 year old senior in college (Math+Comp Sci... kind of Engineering). I spent 2 years away from school but was always quite good in math. I felt mentally behind (not just because I forgot stuff but it seemed harder to visualize things). I felt like I had to spend a lot more time than...
If your computer science class is Software Engineering, and Assembly Langauge Programming, your math class is Analysis part I, and the rest of the classes are complete BS, then no. It's not possible.
Otherwise, it's not too bad.

Use the definition of matrix multiplication to show that the value of Sk-1k,1 = 1 but Sk-1< k,* = 0 and Sk-1k, >1and<n = 0 => Sk*,* = 0.
Where * means any row and any column.
edit: If you are trying to prove that statement in general, you might want to consider the identity matrix which is...
Do you need an exact answer? You could approximate it very easily by using the volume of a sphere with 12 as it's radius and subtract the volume of a cylinder with radius 7 and height 12?
edit: The exact answer is obtained (one way) by using the equation for a circle (x*x + y*y = r*r, solve for...
They are not all that similar. EM relies on Maxwell's 4 equations, Lorentz Force Law, Waves, and sometimes optics.
All I remember needing to know was those equations (how to derive others, which you will learn) and things like super position. I might be forgetting something though.
It...
In part b, the lim a_n = 0 as n --> inf just means that only those a_n that are contained in V that meet the criteria lim a_n = 0 as n --> inf are contained in the set.
So to prove part b, you just need to show that addition and scalar multiplication are closed in the subspace.
Sorry, I'm not...
Homework Statement
I need to find the basis of W1 + W2 and W1 intersect W2
(It's part of a larger homework problem that I know how to do, but I am stuck on the trivial step...per usual)
W_1 = \left(\begin{array}{c c} x & -x \\ y & z \end{array}\right)
W_2 = \left(\begin{array}{c c} a...
More abstinence from people who shouldn't be parents!
By the time you get these students in Calculus I, you have gotten a student who has developed years of **** poor mathematics. I can't say I was a great mathematician taking calculus I, but I can say I knew what the basic terminology was...
Due to the severity of plagarism (especially because of how graduate school works), I agree with this.
The only hope you have is to retake the course and get the professor to remove the comment from your record.
The ONLY hope for that is (other than a HUGE bribe. . . although most people...
First, don't weight your GPA.
Second, GPA is a very small portion of some schools admissions process. If you have a mediocre GPA but outstanding activities, tests, and the later you are likely to get in.
If you have a strong GPA but weak extra, you are likely to be relegated to a top state...
