![]() ![]() Step 3: Create a table of values from Steps 1 and 2. To do this, you replace the “x” in the formula with the number you choose for x. Step 2: Input your x-values from Step 1 into the function. A good starting point is a few values around zero: -2, -1, 0, -1, 2. It’s up to you what values to choose for your x-values, but pick numbers that are easy to calculate. Sketch the Graph on the Cartesian Plane: ExampleĮxample question #1: Sketch the graph of y = x 2 – 2 on the Cartesian plane. Usually you’ll want to choose integers (whole numbers plus zero and negatives like -10, 3, 1, 7…) because they are easier to work with. Choose your x-values to input into the formula.In order to solve the problem you need to: Let’s say you were given a function like f(x) = x 2 – 2 (or, equivalently, y = x 2 – 2) and asked to sketch the graph on the Cartesian Plane. That is- if you’re really interested in reading more confusing aspects about ordinate and abscissa and the history behind the terms! Sketch the Graph on the Cartesian Plane I really recommend you take a look at Jason Dyer’s blog, where he goes all the way back to Fibonacci (c. While the axes in a Cartesian plane are perpendicular, the axes in an oblique coordinate system are not. The two terms can also be used in an oblique coordinate system.For example, The Journal of Experimental Medicine from 1896 states that “…the abscissa is divided into six to eleven segments, each representing a period of one week, while the ordinate is divided into ten segments representing the abstract units 1 to 10.” In some sciences, like physics and astronomy, some scientists still use that definition. ![]() In earlier geometry classes, the X-Axis was called the abscissa and the Y-Axis was called the ordinate. ![]() For example, Merriam-Webster states an anscissa is “The horizontal coordinate of a point in a plane Cartesian coordinate system obtained by measuring parallel to the x-axis.” Use caution here, as this definition only works with positive numbers!
