nilai fungsi trigonometri

sin 30 = 1/2
tan 35 = tqn (180-45) = tan 45 = 1
cos 45 = 1/2 √2
cos 60 = 1/2
sin225 = sin(180+45) =- si 45 = - 1/2√2
tan 15 = tan (45-30) = 2 - √3

misal
p=  (2 sin 30. tan 135.cos 45
p = 2 (1/2)(1)(1/2 √2)=  1/4 √2

q=(cos 60,sin 225.tan15) = (1/2)(1/2√2)(2-√3)
q = 1/2 √2 -1/4 √6

p/q = (1/4 √2)/(1/2 √2  - 1/4 √6) ....kalikan 4/4
p/q = (√2)/(2√2 - √6)  kalikan akar sekawan
p/q =  √2 ( 2√2 + √6) / (2√2 - √6)(2√2 + √6)
p/q = (4 + √12)/(8-6)
p/q = (4 + 2√3)/(2)
p/q = 2 + √3
