Technical subjects with verified calculations
For students in technical programs, from first year to final exams. The tutor hands every calculation to machine checking and tells you whether it holds.
Mathematics
Functions, derivatives, integrals and vectors for high school and final exams.
Mechanics
Statics, kinematics and dynamics. Solving mechanical systems with verified steps.
Thermodynamics
Heat, gas laws and calorimetry. The tutor hands calculations to machine checking (SymPy).
Fluid mechanics
Pressure, buoyancy and fluid flow. From Pascal's law to the continuity equation.
Mechanical engineering
Machine elements: axles and shafts, bolted joints and gear drives.
Electrical engineering
Circuits, the electromagnetic field and the basics of electronics.
Energy engineering
Heat engines and power machines: internal combustion engines, turbines and pumps.
