Question

Nilai dari tan^(2) π/4 + cos^(2) 0° / sin^(2) π/6 = ...
a. 1/2
b. 1
c. 2
d. 4
e. 8

Answer 1

tan^(2) π/4 + cos^(2) 0° / sin^(2) π/6
= (tan π/4 . tan π/4)+ (cos 0° . cos 0°) / (sin π/6 .sin π/6 )
=( 1/2 √2 . 1 /2 √2 )+ (1 . 1) /(1/2 . 1/2)
= 1/2 + 1 / (1/2)
= 1/2 / (1/2)
=2/1 . 2/1
=4/1
=4
