Roof Structure Question find lengths
I give you a hint. The area of Triangle ABD = area ABC +area BCD Now, call $BD=h$, the height. Then you can find, $CD=\sqrt{4700^2-h^2}$ Thus, area ABD= $(1/2)h(3300 +\sqrt{4700^2-h^2})$ area ABC can

What is the least prime number that is greater than 90?
In mathematics, an integer sequence is a sequence (i.e., an ordered list) of integers.
An integer sequence may be specified explicitly by giving a formula for its nth term, or implicitly by giving a relationship between its terms.

Basic Concept
The SQUARE, CIRCLE, and TRIANGLE primitive shapes are implemented as lists of path operations, which are drawn on a canvas. The new path feature allows new primitive shapes paths to be defined. A
path contains a list of path operations and path commands.

From Wikipedia: RANSAC is an abbreviation for "RANdom SAmple Consensus". It is an iterative method to estimate parameters of a mathematical model from a set of observed data which contains outliers.

Implicit Equation Grapher
Re: Implicit Equation Grapher
First thing I notice is the new warning about the flash player.
It is funny about the known bug. That is just y = x and should graph as a straight line. Mathematica will graph it like that, Geogebra too, but other graphers like this one have the same problem.
