Changing Theta Range now redraws the affected polar graphs. 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 formatting of equations produced by Find Derivative so derivatives of tan(x) and cot(x) graph correctly on reload.Ĩ. Graphmatica is described as 'Is a powerful, easy-to-use, equation plotter with numerical and calculus features:' and is an app. Fixed issues which could cause a fatal error graphing an equation to also corrupt memory or crash the program.ħ. 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. The best known of these is the EPICYCLOID. 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. EPICYCLOIDS, HYPOCYLOIDS, EPITROCHOIDS, AND HYPOTROCHOIDS There are four related classic curves which are generated by one circle rolling about the outside or inside of stationary second circle. The curve is an example of an epicycloid which is a curve closely related to curves called epitrochoids. Fixed bug which could cause the "Guess for off-screen intersection" entered in the Find Intersection dialog box to be ignored.Ĥ. On the page Geometry - Sun, earth and moon, it is shown how to make a model of the path of the moon without using trigonometry.By using trigonometry, you can define the path of the moon as a curve. Fixed a rare memory corruption issue in curve fitting code.ģ. Fixed y=x^(-(2/3)) to be correctly identified as an even power, so it draws both sides of the graph.Ģ.
