Coming soon

We are working on these types of problems or have them planned. The order may change depending on what you need most.

Equations and inequalities

Incomplete quadratic equations by factoring or taking roots (x² = 9) instead of the discriminant.

Integral applications with parameters – general formulas (a sphere of radius r, an ellipse, a cone).
The shaded area and the 3D solid for parametric and polar curves.
Physical applications of derivatives and integrals (velocity, acceleration, work, centre of mass).
The complex form of the Fourier series and the spectrum.
The Riemann and Lebesgue integrals of special functions (the Dirichlet and Riemann functions).

Systems of differential equations given as equations (the applications have them already) and their phase portrait.
The Laplace transform with the Heaviside function, shifts and periodic right sides.

Vectors – magnitude, dot, cross and triple products, angles, areas and volumes.
Matrices – operations, determinant, rank, inverse matrix, eigenvalues and eigenvectors.
Construction problems – triangles, quadrilaterals and circles from given elements, the construction steps and the number of solutions.
Complex numbers in the polar and exponential form, de Moivre's theorem, n-th roots.
Cramer's rule for systems of linear equations.
Functions of several variables, multiple, line and surface integrals.
Exact and numerical result modes (decimals instead of fractions and roots).
Word problems – setting up the equations from the text and solving them.
