Dynamic Geometry Sketch Pad vs Geometry

Sketchpad is a set of mathematics dynamic geometry, mathematical computation, formulas input application. Using mathematical drawing board, you can replace the Ruler mapping, but you can make advanced image and function of the image trajectory, can dynamically change their properties, measure their relative value, you can create custom variables, custom functions, using natural mathematical formula input expression, beautiful, clear, inside it is built up to 25 common mathematical functions. All visual elements are displayed in a scrollable Sketchpad infinite area, Sketchpad area content can be permanently saved as a separate file. This program includes the following features: Formula features: - Sketchpad provides fractional, radical, radical times, index, subscript, A superscripts arranged formula, C and superscripts combination formula, Σ summation formula, Π quadrature formula also provides Greece enter letters, overline formula (expressed segments), the arc formula (expressed arc) and other mathematical formula, the formula can be pre-cut, copy, paste, natural way to enter, the natural way to edit, and consistent operation iOS text edit. File feature - New:Locked - Open:Locked - Save:Locked - Setting Editing feature - Undo - Redo - Delete - Select All - Select parents - Select children View feature - Point type - Line type - Color - Hide - Show all - Unselectable - All selectable - Hide label - Show label - Label Constructure feature - Point on objec - Midpoint - points of intersection - Line segment - Half-line - Line - Parallel line - Perpendicular line - Angular bisector - Circle - Circle of center and radius - Arc on circle - Arc of three point - Locus Transform feature - Mark center - Mark mirror - Mark angle - Mark ratio - Mark vector - Mark distance - Translation - Scale - Rotation - Mirror Measure feature - Length - Distance - Circumference - Arc length - Radius - Squard - Angle - Radian angle - Ratio: the ratio of AB measure of three ABC / AC, unit 1. - Horizontal ordinate - Vertical ordinate - Distance of coordinate Data feature - New Variable: create mathematical variable object, you can enter complex mathematical formulas, execution, subtraction, multiplication, fractions, exponentiation, but you can use the built-in 25 kinds of mathematical functions (sin, cos, tan, arcsin, arccos, arctan, sinh, cosh , tanh, arcsinh, arccosh, arctanh, exp, pow, sqrt, ln, log, round, trunc, sng, abs, min, max, arrange, combine), you can use custom variables, custom functions and parameters for calculating cost per unit (currently only supports cm and angle in radians), to use the constant π, e participate in the calculation. - New Function: Create a mathematical function objects, custom functions, variables with other calculations. Graphics feature - Define coordinate system - Define origin - Define unit length - Define origin and units length - Change graduation on axis - Mark coordinate system - Draw point - Drawing function:2 limit - Draw function curve:2 limit - Independent variable interval Mapping Toolbox functions - Arrow selection tool - Scroll Tool - Point tool - Line Tool - Circle Tool - Label Tool Auto-save feature: -Each step, Sketchpad automatically saved when the program closes workspace content or crash, after the next open draw will automatically restore the previous analysis. Two finger swipe means you can scroll sketchpad content at any time.

The GeometrySolver is not just an app, its a canvas and a book too. This app not only solves the geometric shapes, it also teaches you the formulas related to each geometric shape as well as it draws the geometric shapes when solved. This app is designed by an engineer to the perfection with every details in mind. It calculates side, height, diagonals, apothem, diameter, radius, perimeter, circumference, area, lateral area, surface area, volume. Some shapes have a dedicated interactive tab to play around and draw those shapes of different dimensions. Each geometric shape has its corresponding formulas written beautifully in mathematical way. This is a perfect app for your kids to learn geometry interactively. Draw, solve, share the geometric shapes. Drawn/solved shapes are displayed with their properties (numeric values). The Solve tab of angle is dynamic and interactive. You can touch/drag on the surface to draw an angle or use the slider to draw an angle. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. There are so many common geometric shapes to learn from like square, circle, cylinder, cone, cuboid, pyramid, sphere and more There is also a Study page to help you with learning formulae related to many common geometric shapes. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
