**Title:** Methods for solving systems trigonometric equations with two unknowns with and without a computer
**Keywords:** Systems Trigonometric Equations with Two Unknowns , GeoGebra, ANALYTICAL SOLVING, GRAPHICAL SOLVING**Abstract:** We consider several Systems Trigonometric Equations with Two Unknowns (STETU), solve them graphically by PC and analytically “by pen” and compare the solving methods and comment them. At this stage we don’t aim to evaluate or judge them, but we rather share our experience.
