Definition of rectilinear motion:

Let s(t) is the coordinate of a point “P” at time “T”.

- s'(t) = v(t) Velocity
- s”(t) = v`(t) Acceleration
- |v(t)| Speed (speed is always a positive value)

Fall 2012 semester just began at Santa Monica College. I’m really excited about my classes and what I will learn from/via them.

Taking four classes; early world history, philosophy (early philosophers), pre-calculus, and C programming.

My math professor presented this problem .. nobody was able to complete it for the test the day prior, so this is a review.

So I learned this cool counting trick from my math professor the other day. It’s a method of multiplying I didn’t know existed. If you’re using the internet, you *probably* don’t need to use this.

I’ve been having difficulty with Algebraic Matrices for a couple days now; the textbook and video methods I’ve looked at didn’t help me at all until I found this youtube video:

The definition of **Point-Slope Form** is any equation of the form:

y-y¹ = m(x-x¹)

Note: **There is no graphing**. We seek the equation of the line.

`3x + 7 = 4t - 3`

and

`7x(7+1) - 3t(5-12x)`

Okay, so what is different about the above and why does it matter?

Answer: One you can **solve**, and one you can **manipulate **(such as simplify).
