"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. reflect a flip creating a mirror image of the shape rotate a motion of a certain space that preserves at least one point.Last day before half term yr 8 were using Graph Plotter to attempt the challenges - all were successful /uzNjAszZxs- Heather Scott October 22, 2017 Quadrant I: (x, y), Quadrant II (-x, y), Quadrant III, (-x, -y), Quadrant IV (x, -y) rectangular A 4-sided flat shape with straight sides where all interior angles are right angles (90°). Quadrant I: (x, y), Quadrant II (-x, y), Quadrant III, (-x, -y), Quadrant IV (x, -y) quadrant 1 of 4 sections on the Cartesian graph. (x, y) point an exact location in the space, and has no length, width, or thickness polar a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction quadrant 1 of 4 sections on the Cartesian graph. The formula for rotating a point 270° is:įormula for reflecting over the origin is:įormula for reflecting over the y-axis is:įormula for reflecting over the x-axis is:Ĭartesian a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length coordinates A set of values that show an exact position cos cos(θ) is the ratio of the adjacent side of angle θ to the hypotenuse degree A unit of angle measurement, or a unit of temperature measurement ordered pair A pair of numbers signifying the location of a point The formula for rotating a point 180° is: Then the point (-x, y) is also on the graph Then the point (x, -y) is also on the graphĭetermine symmetric pointIf (x,y) is symmetric to the y-axis: Then the point (-x,-y) is also on the graphĭetermine symmetric pointIf (x,y) is symmetric to the x-axis: The formula for this is below: Polar Coordinates are (r,θ) Determine the abcissa for (3,4)Abcissa = absolute value of x-valueĭetermine the ordinate for (3,4)Ordinate = absolute value of y-valueĮvaluate the ordered pair (3,4)We start at the coordinates (0,0)ĭetermine the quadrant for (3,4)Since 3>0 and 4>0
