Geometry-Solver против Least Squares Curve Fit Использование & Stats
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!

“Least Squares Curve Fit” is a user friendly, free of charge and free of ads app.
User inputs point sets and chooses function types.
Utilizing the Least Squares Linear Regression Method, the app calculates best fit curves, reports equations and draws graphs.
Point sets can be stored in a table and are available after app is closed.
Currently available function types are:
2D:
1. Line.
2. Parabola.
3. Polynomial up to 8th degree.
4. Circle.
5. Conic section (Ellipse or Hyperbola).
6. Trigonometric function as
C + A1*cos(ω*x) + B1*sin(ω*x) + … + An*cos(n*ω*x) + Bn*sin(n*ω*x),
where user can select n between 1 and 8 and enter any ω.
7. Exponential Function.
8. Bell Curve.
3D:
1. Plane.
2. Sphere.
Also, there is an option to choose the Best Fit:
the app goes through all the possible shapes and lists them in order from best to worst fit based on residuals.
In some cases, when the standard Least Squares method with orthogonal projection does not work, best fit for Line, Parabola, Polynomial and Trigonometric functions can be calculated with SVD.
Links to four other free apps by same developers are included in the app:
1. “Matrix Solver Step by Step” Linear Algebra Visual Guide.
2. “Polynomials and Linear Systems” Equation Solver.
3. “GraphMath” Graphing Calculator.
4. “Vectors and Planes” (and Spheres and Ellipsoids) 3D Geometry Guide.
Developers hope to get feedback from users at graphmath@aol.com.
