Math Navigation

This Math app “Math Navigation” is for both who loves math and who hates math.

Feb. 20, 2015 updated
“Distance” in Linear function of Function is added,
“Finding circumcenter” in Q and A of Geometry is added.
“Equations” in trigonometry of Geometry is added.
Matrix section is added.

Jan. 21, 2015 updated
Euler's formula and taylor series are added.

The feature of this app is to learn and get Math by digital technology. The method is to calculate length of a side of triangles, area of triangles or position of x on coordinate repeatedly by yourself via programmed various values on screen. The various values can give us chances to see a question from different angles so that we could easily touch the core of math nature.

This app has two modes: Game and Practice modes.

Game mode has two levels.
Practice mode has ten sections.
