Exact values for trigonometric ratios
... The 30 60 90 and 45 45 90 triangles are familiar tools used to work out the exact values of the trig ratios for those angles (the idea being that, instead of memorizing all the ratios for 30, 60, and 45 , you memorize the proportions on the triangles, do a quick sketch, and then wor ...
