sin and cos are properties of angles. If you have a right triangle such that angle a is opposite of side A, b opposite of B, and c, the right angle, opposite of the hypotenuse, C, sin(a) = A/C, cos(a) = B/C, sin(b)=B/C, cos(b)=A/C, sin(c)=1, and cos(c)=0.
Though I'm sure you haven't learned it, trigonometry is essential to spherical, polar, and cylindrical coordinate systems. Vector calculations rely heavily on trigonometry, as well as 3D graphics.
They're basically only ever used in graal for pretty light effects and movement systems. |
