Yup. Electrical engineering does something similar. The addition and subtraction of voltages, currents, resistance, capacitance, and inductance in AC circuits is basically unworkable without the shortcut of converting the sinusoidal waves into imaginary phase angles and doing math on them, and then converting them back to sinusoidal waves as necessary.
