Abstract:

Sinusoidal circuit analysis is very common in Alternating Current (AC) electrical circuit analysis and so close to the term of phasor concept using complex frequency, which is mainly use trigonometry figures such as sin, cos, and tangent, for calculations. One of the most important tasks that we will meet e.g. finding phase angles using inverse tangent formula. The author presents this paper to introduce a mathematic solution derived from basic concept of trigonometry, to solve circuit analysis problems related to phase angles and inverse tangents.
