【實用教育app】GraphMe HD: Graphing Calculator|最夯免費app-綠色工廠好玩App

*****LIMITED TIME SALE! 50% OFF*****Powerful and easy to use graphing calculator that allows you to plot real-valued functions, trajectories, and even vector fields on the cartesian plane. Everything with amazing retina graphics.GraphMe takes full advantage of the multitouch capabilities of the device in a simple and intuitive way, like controlling the parametric interval of a trajectory with a simple finger gesture.Features:• You can graph in the cartesian plane the following type of functions: Real-valued of a real variable (including functions in polar coordinates)TrajectoriesVector fields • Drag to pan, pinch to zoom and shake the device to restore the original position.• Plot up to four graphs of real-valued functions at once, with different colours to distinguish them. • Plot up to four graphs of functions in polar coordinates and change the angle variable with a gesture. Compare them alongside your functions in rectangular coordinates. You can change to polar coordinates with a swipe to the left on top of the real-valued functions fields.• Create tables of values within the real functions plotter. • Graph inequalities.• Send your graphs as images through email, or save them to your photo gallery with amazing retina quality.• You can change the parametric interval of your trajectory using a simple gesture, and see the changes on the fly. Also, you can change the angle of your polar functions dynamically.• You can use the following functions: cos, sin, tan, exp, log, sqrt, pow, abs, csc, sec, cot, asin, acos, atan, sinh, cosh, tanh, csch, sech, coth, floor, ceil and round. • Take full advantage of screen size, hiding the functions panel with a simple swipe.• Night mode.• Customised keyboard.• More features to come!Supported languages: English, Spanish.
