I'd like to show a graph to an expert (such as an automotive electrical circuit engineer, if there is such a thing) and ask him/her to explain the relationship in my experiments. When people hear my story, their eyes glaze over and they turn off listening. Where P1 is a few minutes, P2 is a few minutes where P1 is overnight (20 hours), P2 is 2-3 days P1 is 5 days, P2 is 11 days P1 is 10 days, P2 is 22 days and finally, P1 is 5+ months, P2 is 5+ months. My experiments have shown where P1 is greater, P2 is greater. P1 is the time period in days or partial days wherein the car battery is completely disconnected P2 is the time period, upon reconnecting the battery, wherein the check engine light remains OFF until it illuminates ON. I've discovered there may be some sort of linear relationship between two time periods (P1 and P2), and I'd like to show it on a graph and I'm seeking help in that regard. I've assumed my problem is not typical and I'm searching for a clue, any clue. "My question may not seem mathematical in nature, but here goes: mechanics and auto technicians are stumped trying to find the problem with my car engine that results in the check engine light being ON all the time. "Can't we plot parametric equations in this plotter?

Thank you for making Transum free and available on the internet. I find it mesmerizing that an equation can give amazing results. When writing the equation, cos(x²)=sin(y²) the following graph is plotted. For now, I love plotting them even though I don't understand them well. When I know more about Trigonometry I will understand why these graphs are the way they look. Although I don't understand much about trigonometric graphs, I have plotted some trigonometric graphs with beautiful patterns. I am very thankful for Transum and through this, my passion for math has increased. "Hello, I am Soumi Dana, currently studying in 8th grade.
Unfortunately it only plots the positive answer to the square root so the circles would not plot. "Absoultely brilliant got my kids really engaged with graphs. "First of all, congratulations for the beautiful job! But I have a question: is there a way to save/download the graphics? thus adjusting the coordinates and the equation. "Would be great if we could adjust the graph via grabbing it and placing it where we want too. "It would be nice to be able to draw lines between the table points in the Graph Plotter rather than just the points. You can use formulas, including the Distance Formula, to get precise measurements of line segments on the grid.Last day before half term yr 8 were using Graph Plotter to attempt the challenges - all were successful /uzNjAszZxs- Heather Scott October 22, 2017 His Cartesian grid combines geometry and algebra. To take us from his Theorem of the relationships among sides of right triangles to coordinate grids, the mathematical world had to wait for René Descartes. Pythagoras was a generous and brilliant mathematician, no doubt, but he did not make the great leap to applying the Pythagorean Theorem to coordinate grids. You are also able to relate the Distance Formula to the Pythagorean Theorem. Now that you have worked through the lesson and practice, you are able to apply the Distance Formula to the endpoints of any diagonal line segment appearing in a coordinate, or Cartesian, grid.
You need not construct the other two sides to apply the Distance Formula, but you can see those two "sides" in the differences (distances) between x values (a horizontal line) and y values (a vertical line). The Distance Formula gets its precision and perfection from the concept of using the angled line segment as if it were the hypotenuse of a right triangle formed on the grid. You really should be able to take the last few steps by yourself. Here are the beginning steps, to help you get started: We will not leave you hanging out on a diagonal. You need not even have a coordinate grid in front of you to use the Distance Formula, so long as you have both sets of coordinate points. Let's use our line's endpoints, ( 1, 3 ) and ( 7, 6 ): The Distance Formula is a special application of the Pythagorean Theorem.Īll you need to do is plug the coordinates in very carefully. That leaves a calculation about the hypotenuse, your given diagonal. What this is really doing is calculating the distance horizontally between x values, as if a line segment was forming a side of a right triangle, and then doing that again with the y values, as if a vertical line segment was the second side of a right triangle. The expression ( x 2 - x 1 ) is read as the change in x and ( y 2 - y 1 ) is the change in y.
