## Indefinite Integrals

Posted by Jeff on Oct 11, 2009 in Calculus, Math

TweetWhat are indefinite integrals used for? In integral can be thought of as an area underneath a curve.  Integrals are often used to manipulate position, velocity, and acceleration equations to estimate different situations.  If you are given an equation that represents the velocity of a golf cart driving, like so: (the ‘ in y’ represents [...]

TweetThis is a very simple post and a very simple subject, but every once in a while even the experts need to be reminded how to do simple addition and subtraction with vectors.  Let’s go ahead and specify a couple vectors that we can work with. Vector In MATLAB: >>A = [1 2 4]; Vector [...]

## Volume of Ellipsoid – MATLAB

Posted by Jeff on Aug 31, 2009 in Calculus, MATLAB

TweetThis is how you calculate the volume of an ellipsoid with the following equation. rmax = 1; V = 0; step = 0.02; A = 5; B = 10; C = 15; for x= -5 : step : 5 for y = -10 : step : 10 for z = -15 : step : 15 [...]

## Derivatives

Posted by Jeff on Jul 29, 2009 in Calculus, Math

TweetOne of the most important calculus concepts to learn is derivation.  Here I will show you how to calculate some simple derivatives.  The derivative looks like this and can be read as “derivative with respect to x” so if you have a function and you are supposed to perform then you are going to be [...]
