## Mathematics for engineer

**Areas and Volumes**
The module contains considerable set of frequently used plane figures and solids, for which with appropriate formulas it is possible to determine areas, volumes and surface areas respectively.

**Diagram Multiplication**
The module is intended to multiply diagrams of internal (unit and load) forces of various shape for solving statically indeterminate systems by force method. Computation is made by three methods: Vereshchagin formula, Mohr integral and universal numerical method.

**Linear Algebra**
The module is intended to solve main problems of linear algebra:

• to multiply matrix by matrix (vector);

• to compute the determinant of a matrix;

• to invert a matrix;

• to determine eigenvalues and eigenvectors;

• to solve a set of linear equations.

**Polynomial Roots**
The module is intended to determine complex root of polynomial that consists of real and imaginary components. Polynomial order is limited up to 36.

**Function Interpolation**
The module is intended to interpolate on nonuniform mesh the function defined in tabular form and compute values of interpolated function from arbitrary arguments.

**Advanced Calculator ESPRI**
The module presents advanced set of mathematical functions and options, such as:

• to compute expressions defined by the user as formulas;

• to compute hyperbolic function;

• to convert different measurement units;

• to compute definite integral for arbitrary function.
