Quadratic equation graph key points: Image title: Graph of y = ax² + bx + c having real roots and positive a with key points labellled by CMG Lee. Roots and y-intercept are in red, turning point and axis of symmetry are in purple, and focus and directrix are in blue.
English: This file represents a general sine function. There is a coordinate plane with "x" the X-axis and "y = f(x)", the Y-axis. The X values go from -2π to 2π, and the Y values go from -2 to 2. There is a sine curve oscillating around its midline m represented by an orange straight line. In blue, there is a crest point A, a neighbouring ...

English: SINE and COSINE-Graph of the sine- and cosine-functions sin(x) and cos(x). One period from 0 to 2π is drawn. x- and y-axis have the same units. All labels are embedded in "Computer Modern" font. The x-scale is in appropriate units of pi.
See Wikipedia graph-making tips. Then I opened the resulting SVG file in Inkscape, copy and pasted the Unicode π characters and modified those labels by hand, changed the line colors, brought the plot lines to the top, made all the lines 3 px wide, made the grid lines 2px wide and 50% transparency. I also manually reconnected the grid lines ...
