Question

sin²(60)+tan²(30)-2 evaluate​

Answer 1

Answer:

=- 11/12

Step-by-step explanation:

SIN^2(60) + TAN^2(30) - 2

PUTTING VALUES WE WILL GET THE ANSWER

(ROOT 3/2)^2 +  (I/ ROOT 3)^2 - 2

3/4  + 1/3 - 2

TAKING LCM

9+4-24/12 = -11 /12

Answer 2

Answer:

sin 60 = $\sqrt{3} /2$  squar will be 3/4

tan 30= $1/\sqrt{3}$ squar will be  1/3

3/4+1/3-2=-11/12
