Ah, in our state board we never memorized a table, we drew the triangles. For 0° and 90°, see the shadow of a stick—when it's straight up, no shadow, that's your zero. For 30°, 45°, 60°, just draw the right triangles with sides 1,√3,2 and 1,1,√2, then write the ratios. My son always said this way, the logic sticks, kasam. It's like painting my lamps—you remember the shape of the bottle, not a list of colours.
