Grapher Free 1.4.4b APK

アプリの説明

Grapher is a fast and effective equation plotter, capable of drawing any function, solving equations and calculating expressions. Especially if you're a student, teacher or engineer, this app is made with you in mind! A wide range of predefined functions is available, including trigonometric & hyperbolic functions, polar coordinates, differentiation and more. Anything you type will be processed and displayed instantly by a powerful math engine, in both 2D and 3D modes. Furthermore, functions can reference each other by their name.As I strive to make Grapher fit your needs, any feedback and bug-reports are greatly appreciated. This free version has most but not all features; please consider buying Grapher Pro to enjoy awesome extensions such as parameter sliders and complex plotting!Curve types• Function (e.g. parabola, sine wave)• Polar (e.g. rose, spiral)• Parametric (e.g. ellipse, Lissajous) on the xy-plane or rθ-plane• Implicit equation (e.g. conic sections)• Implicit inequality (e.g. half-plane)• 3D function (e.g. paraboloid)• 3D parametric curve (e.g. helix)• 3D parametric surface (e.g. sphere, hyperboloid)More features• Equation solver (numerical)• Find roots, extrema and intersections with other functions• Functions can reference each other, e.g. g(x)=2*f(x+1)• Custom math keyboard• Auto-detect input type• User variable support for both numbers and functions• Adjustable parameter range (for cartesian, polar & parametric curves)• Input history• Plot up to 28 graphs at once• Differentiation (numerical)• Trace graph• Capture screenshotsNote: Mathematical functions should be typed by their names, for example sqrt(x) means √x. Hold a key to see all function names starting with that letter. If something is unclear, be sure to check out the 'Help' page as all details are summarized there.
