Question

4/3 tan² 60° + 3cos² 30° - 2 cosec² 60° – 3/4 cot² 45°


​

Answer 1

Answer:

17/6

Step-by-step explanation:

tan 60= root 3 , cos 30= root 3/2 , csc 60= root

2/3 , cot 45= 1

according to problem ,

4/3 (root 3^2) + 3 (root 3/4^2) - 2 ( 2/ root 3^2) -

3/4 (1^2)

4/3×3 + 3×3/4 -2×4/3 - 3/4×1

4 + 9/4 - 8/3 - 3/4

(48 + 27 - 32 - 9)/12

34/12

17/6
