Aaron Griffin Math 4091A March 17‚ 2015 The Cartesian Coordinate System Linear inequalities (statements such as “4≤X+10<18”) can be represented graphically along a number line. In similar manner‚ a linear equation in two variables (this being the form ax+by=c) can also be represented graphically‚ using two axes; the x axis‚ the horizontal plane‚ and the y axis‚ the vertical plane. There are memory tricks with which to distinguish the x from the y axis and remember their horizontal and vertical

* Cube In geometry‚ a cube is a three-dimensional solid object bounded by six square faces‚ facets or sides‚ with three meeting at each vertex. As the volume of a cube is the third power of its sides ‚ third powers are called cubes‚ by analogy with squares and second powers. A cube has the largest volume among cuboids (rectangular boxes) with a given surface area. Also‚ a cube has the largest volume among cuboids with the same total linear size (length+width+height). * Parts:

and ellipse. The circle is sometimes categorized as a type of ellipse. In mathematics‚ a conic section (or just conic) is a curve obtained as the intersection of a cone (more precisely‚ a right circular conical surface) with a plane. In analytic geometry‚ a conic may be defined as a plane algebraic curve of degree 2. There are a number of other geometric definitions possible. One of the most useful‚ in that it involves only the plane‚ is that a conic consists of those points whose distances to some

As some of my peers might know‚ geometry is definitely not my favorite subject in math. I have always struggled with geometry‚ especially with memorizing formulas to solve problems such as finding volume‚ surface area and more. I always found formulas to be such a bother and even after learning one and mastering it somewhat‚ I usually ended up forgetting the formula. Fortunately‚ the formulas that I had the most trouble with‚ being volume‚ surface area‚ and area‚ have finally began to stick with

shows that Pierre de Fermat (1601-1665)‚ also a French mathematician and scholar‚ did more to develop the Cartesian system than did Descartes. The development of the Cartesian coordinate system enabled the development of perspective and projective geometry. It would later play an intrinsic role in the development of calculus by Isaac Newton andGottfried Wilhelm Leibniz.[3] Nicole Oresme‚ a French philosopher of the 14th Century‚ used constructions similar to Cartesian coordinates well before the time
