Desmos can display those as circles, a smooth line through the points, or a smooth line with circles. However, when I try to translate your code to my code, Im getting lost. These rotations are denoted by positive numbers. So x prime equals zero, and y prime equals zero. Rotating about a point in 2-dimensional space. Lets take a look at the Examples below: Step 1: First, lets look at our point of rotation, notice it is not the origin we rotating about but point k! To perform rotation around a point different from the origin O (0,0), let's say point A (a, b) (pivot point). Note that the direction of rotation (CW or CCW) doesnt matter for 180 and 360-degree rotations, since they will both bring you to the same spot (more on this later). Yes, a button click to do the rotation (without animation) would work. New figure. The amount of turn is specified by the angle of rotation and this must be given a direction, either clockwise or anticlockwise . To understand where our triangle is in relation to point k, lets draw an x and y axes starting at this point:if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'mathsux_org-box-4','ezslot_6',176,'0','0'])};__ez_fad_position('div-gpt-ad-mathsux_org-box-4-0'); Step 2: Now lets look at the coordinate point of our triangle, using our new axes that start at point k. Step 2: Next, lets take a look at our rule for rotating a coordinate -90 and apply it to our newly rotated triangles coordinates: Step 3: Now lets graph our newly found coordinate points for our new triangle . Try x^3 instead of x^2 and you'll see that the graph flips every time you rotate the green point past 0 or 180 degrees. My vertical distance is 5-(2)=7. That is perfect.
