Question

4/3 ( tan60)2 - 4 (sin60)2

Answer 1

Answer:

4/3(tan 60°)^2 - 4(sin 60°)^2 = 1

Step-by-step explanation:

tan 60° = √3

sin 60° = √3/2

Then according to the question,

4/3(tan 60°)^2 - 4(sin 60°)^2 =

= 4/3( √3 )^2 - 4( √3/2 )^2

= 4/3( 3 ) - 4( 3/4 )

= { 4/3 × 3 } - { 4 × 3/4 }

= 4 - 3

= 1

Hence the required answer = 1
