![]() ![]() ![]() ![]() Note that the point P can be anywhere in relation to the interior circle. Fixed formatting of equations produced by Find Derivative so derivatives of tan(x) and cot(x) graph correctly on reload.Ĩ. A hypotrochoid is a roulette traced by a point P attached to a circle of radius b rolling around the inside of a fixed circle of radius a, where P is a distance h from the center of the interior circle. The best alternative is Wolfram Alpha, which is free. There are more than 25 alternatives to Graphmatica for a variety of platforms, including Windows, Mac, Linux, Online / Web-based and iPad. Fixed issues which could cause a fatal error graphing an equation to also corrupt memory or crash the program.ħ. Graphmatica is described as 'Is a powerful, easy-to-use, equation plotter with numerical and calculus features:' and is an app. You can of course add explicit parentheses around function parameters to clarify your intent.Ħ. For instance, y = sinx cosx now parses as y=(sin x)*(cos x) rather than y=sin(x*cos x). Adjusted associativity of implied function parameters to assume that a factor which contains another function call was meant to multiply the first function call, not the function parameter. The single shared point is now evaluated to see if it is an intersection or not.ĥ. Fixed bug which caused Find Intersection on two curves with only a single point of their domains in common to display a spurious "Cannot solve this equation using Newton's method" error. Fixed bug which could cause the "Guess for off-screen intersection" entered in the Find Intersection dialog box to be ignored.Ĥ. The parametric equations for a hypotrochoid are. Fixed a rare memory corruption issue in curve fitting code.ģ. The Roulette traced by a point attached to a Circle of radius rolling around the inside of a fixed Circle of radius. Fixed y=x^(-(2/3)) to be correctly identified as an even power, so it draws both sides of the graph.Ģ. ![]()
