Using a trigonometric identity, since in the first quadrant and in the third quadrant the sine and the cosine have the same sign, is always positive.
It is given by:
In the first quadrant(0° < θ < 90°) and in the third(180° < θ < 270°), the sine and the cosine have the same sign, hence the multiplication is positive and is always positive.
