WebSo at point (1, 0) at 0° then the tan = y/x = 0/1 = 0. At 45° or pi/4, we are at an x, y of (√2/2, √2/2) and y / x for those weird numbers is 1 so tan 45° is 1. . Those two rays are always pi apart. Therefore tan (x) = tan (x+pi*n) for any value of n because the rays of all of the lines will have the same slope. WebTrigonometric graphs - Higher.
