DYsolve is a powerful notepad-style scientific calculator - it allows you many high-school and engineering stuff like vectors, matrices, X-Y graphs, integrals, limits, differential equations and more. All calculations appear on the worksheet as formatted, and can be saved, or sent to another s.

There are ready calculation templates for several math problems, all you need is just to change input values for your case. DYsolve is also used to execute study examples from "noskovtools.com" - online education resource. Theory plus interactive calculation document is very efficient way to study.

Alternative Scientific Calculator is built inside for those who likes more classical style. It computes expressions of any difficulty, saves history, uses previously defined constants. Expression appears as formatted together with result while typing new symbols.

DYsolve is a good choice for students and engineers. The workflow if very similar to Matlab. Application is based on a powerful core, which allows to construct complex expressions, and use wide range of functions.

Main app features are:
- You can create calculation document of any difficulty, without limitations.
- Offline Library provides fast solutions for Mathematical and Physical problems.
- All expressions are visualized as formatted, thus document can be used as calculation report.
- Document can be saved locally or on the server, making it available from another devices. You can send calculation document to your friends, and they will execute calculation flow in one click.
- A 64-bit floating point numbers are used in calculation process.
- There is a good offline - one can use quick guide, basic guide, library with examples, and video-tutorials as well.
- Built-in alternative Scientific Calculator - computes expressions of any difficulty and can save calculation history.

On the worksheet you can:
- Compute mathematical expressions, using a wide range of standard and special math functions.
- Define Variables - constant or depending on other variables.
- Define Functions - with any number of arguments. Functions then can be plotted or used in calculations.
- Define piecewise-continuous Functions (when function has several continuous definitions on different intervals).
- Define Vectors - one-dimensional arrays.
- Define Matrices - of any size. Available Matrix operations are: multiplication, determinant, inverse matrix, transpose matrix.
- Compute definite integrals.
- Compute Limits of a functions
- Create X-Y Plots - plot function, plot two vectors, and other possibilities.
- Compute logical expressions of any diffuculty by using AND, OR, NOT, <, <=, >, >=, ==, != operators.
- Add single-line comments to create a comprehensive calculation report.
- Solve ordinary differential equation systems (Euler 1-st and 2-nd order explicit solvers).
- Execute "for", "while" loop blocks. Nested loops are possible as well; "break" and "continue" operators are available.
- Execute "if/else" blocks.
