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

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. NOTE: For this free version, modifying trajectories, vector fields and some other options are locked, but you can try the grapher with the preloaded functions, as well as plot a wide variety of real-valued functions. You can buy the full version anytime.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) Trajectories Vector fields • Drag to pan, pinch to zoom and shake the device to restore the original position. • Plot up to two graphs (four on full version) of real-valued functions at once, with different colours to distinguish them. • Plot functions in polar coordinates (four on full version) 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. • Graph inequalities. • Send your graphs as images through email, or save them to your photo gallery. • 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 and cot, asin, acos, atan, sinh, cosh, tanh, csch, sech, coth, floor, ceil and round. • Night mode.• Customised keyboard.• More features to come! Supported languages: English, Spanish.
