Size: Calculus f '(a) f ' f '' ∫ f ∑ f right right left middle trapezoidal lower upper a b n: 10 xy × Help Drag to Pan Mouse Wheel to Zoom Trace points are draggable (trace). Right click to remove trace points. Type in an h when finished creating a trigonometry function to turn it into it's hyperbolic form Type (3,2) to plot a point (movable). Type line AB to graph a line through points A and B. Type segment AB to graph line segment AB. Type sector ABC to graph a sector of a circle with center A, and endpoints B and C Type circle AB to graph a circle with center A through B. Type parabola ABC with focus A and line through B and C. Type ellipse ABC with foci A and B through C. Type hyperbola ABC with foci A and B through C. Type lagrange ABCDE for Lagrange Polynomial through pts. Type triangle ABC with points A, B, and C. Type x = 3 for draggable vertical line (VLT). Conic Sections through points are dynamic. Conic Sections are constrained using trace points. Type f(x)= to define functions. Note: You can type any name with (x) at the end of it to make it into a defined function Type f(3) to evaluate functions. Calculus operations are dynamic as well. Hit refresh to start over. 🙂 More capabilities coming soon.
