Answer 2

sin^2 (30) . cos^2 (45) + 4 tan^2 (30) + 1/2 sin^2 (90) - 2 cos (90) + 1/24

At the end, I have mentioned all the values of the trigonometric ratios.

Put them here:

(1/2)^2 . (1/√2)^2 + 4 (1/√3)^2 + 1/2 (1)^2 - 2(0) + 1/24

Solve it further to arrive at the solution:

=> (1/4).(1/2) + 4/3 + 1/2 + 1/24

=> 40/24

=> 5/3

Thus, this value tends to 2 and isn't exactly equal to 2.

Ratios:

sin 30 = 1/2

cos 45 = 1/√2

tan 30 = 1/√3

sin 90 = 1

cos 90 = 0
