This app is able to solve problems of analytical geometry of medium difficulty. The app, also, contains theoretical references concerning the equation of a line, of a parabola, of a circumference and ellipse. The app is able to solve the following problems:
1. With regard to the geometric line, the app is able to calculate the equation of a line that passes through two known points. You can write the coordinates of the points and the app will write the equation of the line, in its canonical form "ax + by + c = 0"
The app is also able to write the equation of a line, when the coordinates of a point on the line are known and the her slope
2. As for the parabola, with the following equation: y = ax ^ 2 + bx + c, you can write the coefficients "a", "b" and "c" and the app is able to calculate the coordinates of the point "fire" , of the point "summit" and the equation of the directrix.
3. Regarding the circumference, the app is able to calculate the equation of a circumference, knowing the coordinates of three generic points.
The app is also able to calculate the equation of a circumference, which is tangent to a straight line, of a given equation, knowing the coordinates of the center and knowing the distance between the center and the line.
4. Concerning the ellipse, having the following equation " x^2 / a^2 + y^2 /b^2 = 1" the app, knowing the abscissas of the two fires and the major semiax, is able to calculate the semiax minor and the eccentricyty.
