how were they able to rewrite the angles into pi/4 minus pi/6 ?

[dark locust]

pi/4-pi/6=3pi/12-2pi/12=pi/12

Same as he said but since 2 and 6 are multipliers of 12

english is 3'd language

multipliers of 12: {,1,2,3,4,6,12}

from there you could do all the couples of it

OHHHH i see thank you

It's just algebra tricks

Most of the math we get taught are of reverse methods of solving so we'd get the answer

It's just implementing that way of thinking
