Question

Evaluate :
sinsquare(60°) – cossquare(30°) + Tansquare (30°)​

Answer 1

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 2

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
