Graphing Systems of Equations - YourTeacher.com - Algebra Help
For a complete lesson on graphing systems of equations, go to www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to solve a system of linear equations by graphing. The first step is to graph each of the given equations, then find the point of intersection of the two lines, which is the solution to the system of equations. If the two lines are parallel, then the solution to the system is the null set. If the two given equations represent the same line, then the solution to the system is the equation of that line.

Converting to Slope-Intercept Form and Graphing - YourTeacher.com

Follow us at Facebook www.facebook.com Follow us at MySpace: www.myspace.com In this lesson, students learn to convert a linear equation to slope-intercept, or y = mx + b form, by getting y by itself on the left side of the equation. For example, to convert the equation x -- 3y = -12 to y = mx + b form, the first step is to subtract x from both sides to get --3y = -x -- 12. Notice that the x term is positioned before the number on the right side of the equation so that the equation will eventually match up with y = mx + b form. Next, divide both sides by --3 to get y = 1/3 x + 4. Now the problem is in y = mx + b form, with m = 1/3 and b = 4, and the line can be graphed using the slope and y-intercept.

Graphing Quadratic Functions - YourTeacher.com - Algebra Help
OUR LESSONS MATCHED TO YOUR TEXTBOOK/ STANDARDIZED TEST: www.yourteacher.com Students are introduced to the parent graph for quadratic functions y = x^2. Students then learn how to graph quadratic functions, such as y = x^2 + 2, and how to identify the vertex, minimum, x- and y-intercepts, axis of symmetry, one pair of symmetric points, and the domain and range of the graph. Finally, students are asked to compare their graph with the parent graph for quadratic functions.

Minecraft Scientific/Graphing calculator - Sin Cos Tan Log Square root
Hello there! (Reddit name: MaxSGB) Here is the project I've been working on ^.^ Specs: 6 digit addition and subtraction, 3 digit multiplication, division and trigonometric/scientific functions. (The reason these are only 3 digits is because multiplication and division would take a long time to decode/complete/encode. Also, the fraction display is hard enough to build for 3 digits, let alone 6 - 6 digit RAM would not only be massive, but a bit pointless since the curves follow the same pattern surrounding the peaks.). Graphing y=mx+c functions, quadratic functions, and equation solving of the form mx+c=0. The screen and keypad were always meant to be the main feature of this machine. The main display boasts 25 digits. Square root signs are displayed and can change to accommodate any number of digits. Square root signs, add, minus, multiply and divide signs are displayed at appropriate times, and there is a full fraction display. The 7-segments for the fractions are the smallest possible, being only 3 wide, and stackable vertically and horizontally. I made a custom texture pack for the keypad, and made wooden pressure plates invisible in order to get the best effect. The calculator itself is just over 250x200x100 blocks. It contains 2 6-digit BCD number selectors, 2 BCD-to-binary decoders, 3 binary-to-BCD decoders, 6 BCD adders and subtractors, a 20 bit (output) multiplier, 10 bit divider, a memory bank and additional circuitry for the graphing function.

To check out our full Trig & Pre-Cal video course, with 150 videos included, refer to: www.mindbites.com . This lesson introduces the graphs of all the other trigonometric functions (cosecant, secant, tangent, cotangent), using the sine and cosine graphs for points of comparison. Professor Burger shows you how to graph tanx using the identity tanx = sinx/cosx. This graph has asymptotes at all the multiples of Pi/2 and a period of Pi/absolute value of b. Next, you learn to graph secx, which is equal to 1/cosx. This means that secant has an asymptote anywhere cosx = 0. Next, Prof. Burger graphs cosecant, using the identity that cscx = 1/sinx. This graph is identical to secx, but shifted, like the relationship between sin and cos. Finally, you will learn to graph cotx, which is equal to 1/tanx. This means that there will be asymptote where tanx = 0, and zeros where tanx has asymptotes. Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, Precalculus.

Graphing Linear Inequalities - YourTeacher.com - Algebra Help
For a complete lesson on graphing linear inequalities, go to www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to graph inequalities in two variables. For example, to graph y is less than x + 2, the first step is to graph the boundary line y = x + 2, using the chart method from lesson 4B. Note that greater than or less than means that the boundary line will be dotted, and greater than or equal to or less than or equal to means that the boundary line will be solid. To determine which side of the boundary line to shade, substitute a test point, such as (0, 0), into the original inequality, y is less than x + 2. Since (0) is less than (0) + 2, or 0 is less than 2, is a true statement, the side of the line that contains the point (0, 0) is shaded.
