Answer:
1/3
Step-by-step explanation:
sin^2(60) - cos^2(30) + tan^2(30) =
(sin60)^2 - (cos30)^2 + (tan30)^2 =
(√3/2)^2 - (√3/2)^2 + (1/√3)^2 =
3/4 - 3/4 + 1/3 = 1/3

Answer:
Step-by-step explanation:
= sin^2(60) - cos^2(30) + tan^2(30)
= (sin60)^2 - (cos30)^2 + (tan30)^2
= (root3/2)^2 - (root3/2)^2 + (1root√3)^2
= 3/4 - 3/4 + 1/3
= 1/3
