## Definite Integral Application Formulas

Some formulas from my applications of definite integrals section of my calculus book.

This formula will produce the area of the shape.

## Rectilinear Motion

Definition of rectilinear motion:

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

1. s'(t)   = v(t)     Velocity
2. s”(t) = v`(t)    Acceleration
3. |v(t)|                 Speed   (speed is always a positive value)

## Techniques of Differentiation [Quotient Rule]

My Calculus 1 professor taught me a cool trick for finding the derivative of a quotient.
Dx[(4X-5)/(3X+2)] =

## Excited

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.

## How to multiply digits 6-9 using only your hands

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.

## Matrices – Gauss-Jordan Elimination Method

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:
