Step-by-step engineering calculator for Ohm's Law, DSP, antennas and more.

EngiCalc turns the tedious algebra of engineering coursework into a transparent, step-by-step process. Where most calculators hand you a black-box answer, this one shows the Given, the Formula, and the Substitution — a small but meaningful shift for students learning the method, not just the number. Built for electrical, communications, DSP, and control disciplines, it fills a real gap between textbooks and heavyweight tools like MATLAB.
