There are two ways to take a vector product. One is by taking their dot product, which yields a scalar, and the other is by taking their cross product, which yields another vector. Which product is used depends on the particular scenario and what quantity you are trying to find. Th...
find the maximum of all points constrained to lie along a circle. Solving this calls for my boy Lagrange, but all in due time, all in due time: enjoy the gradient for now. The key insight is to recognize the gradient as the generalization of the derivative. The gradient points to the ...
Surface: This is the boundary the flux is crossing through or acting on. The boundary could be a sphere, a plane, even the top of a bucket. Notice that the boundary may not exist — the top of a bucket traces out a circle, but the hole isn’t actually there. We’re considering th...
The water flows in a downward direction, and some of it will fall directly into the drain, but other water droplets will circle the drain. Now, imagine that each water molecule that leaves the faucet has a vector arrow attached to it which represents the motion of the molecule. The arrows...
CrossCross Product of two vectors. DistanceReturns the distance between a and b. DotDot Product of two vectors. LerpLinearly interpolates between two points. LerpUnclampedLinearly interpolates between two vectors. MaxReturns a vector that is made from the largest components of two vectors. ...
This situation is shown to the right, where the normal is n, and the vector that is directed towards the light source (yellow circle) is called l. Lambert's law states that the "brightness leaving the surface" is proportional to cosθ, (4.1) which can be expressed as cos...
(1)In computer graphics, a line designated by its end points (X-Y or X-Y-Z coordinates). When a circle is drawn, it is made up of many small vectors. Seevector graphicsandgraphics. (2)In matrix algebra, a one-row or one-column matrix. ...

The fact that C is a closed path is indicated by the small circle on the integral sign. Example 18.7 Using Green's theorem find the integral ∮CF⋅dr where F = (3x2, −4xy), and C a path clockwise along the perimeter of the rectangle 0 ≤ x≤ 4, 0 ≤ y≤ 1. Solution We...
