WebJan 29, 2024 · In the case of the tangent function, tan ( θ) is simply the slope of the terminal side of θ, when the angle is in standard position. Slopes can be negative, therefore tangent values can be negative. As for cosines, if you believe the double-angle formula for cosine, apply it to a 60 ∘ angle, and see what happens! WebAug 21, 2009 · degrees = (degrees + 360) % 360; // +360 for implementations where mod returns negative numbers Explanation. Positive: 1 to 180. If you mod any positive number between 1 and 180 by 360, you will get the exact same number you put in. Mod here just ensures these positive numbers are returned as the same value. Negative: -180 to -1
