SINE WAVE

AS THE POINT MOVES IN THE CIRCLE, THE ANGLE CHANGES FROM 0 TO 2 PI OR 0 TO 360 DEGREES. THE SINE VALUE CHANGES FROM 0-1-0-(-1)-0. HENCE SINE CURVE PRODUCES A WAVY LINE. AS YOU SEE IN THE PICTURE, CIRCULAR MOTION, OSCILLATIONS, VIBRATIONS AND WAVE MOTIONS ARE SIMILAR. SO MOST OF THE PHYSICS PHENOMENA ARE REPRESENTED BY SINE FUNCTION.
