\( \cos (30), \cos (45), \cos (90), \cos (180), \cos (270), \cos (360), \cos (0) \)
\(\tan (60), \tan (30), \tan (45), \tan (90), \tan (180), \tan (270), \tan (360), \tan (0)?\)

There's an easy way! check out comments below to see how.

Answer 1

i hav already memorized them lols

Answer 2

if u making a good tutorial try easy way for sin 18,15,36 hehe

Answer 3

first draw a 30-60-triangle

Answer 4

we let the side opposite 30 be equal to 1, the side opposite 90 equal to 2 and the side opposite 60 be equal to \(\sqrt 3\)
