Answer:

Just remember some values

tan30 = 1/√3

tan 60 = tan(90-30)= cot 30 = √3

cos60 = 1/2

tan 45 = 1

So

4/3 tan2 30 + sin2 60 - 3cos2 60 + tan2 60 3/4. - 2 tan2 45

= 4/3 × 1/3 + sin2 60 + cos2 60 - 4 cos2 60 + 9/4 - 2

= 4/9. + 1 - 4/4 + 9/4 -2

= 4/9 +1-1 +9/4 -2

= 16 + 81 - 72)/36

= 25/36
