Solution Is : Sin A = X * cos A X = sin A / cos A = tan A

Find the value of sin²30 cos245 + 4 tan230 + (1/2) sin290 - 2 cos290 + 1/24 .

a) 3
b) 4
c) 2
d) 1

✔Answer

✔Solution

Correct Answer Is : 2

Solution Is : Sin230 cos245 + 4 tan230 + (1/2) sin290 - 2 cos290 + 1/24 = (1/2/2 x (1/√2)2 + 4 (1/√3)2 + (1/2) (1)2 - 2 (0)2 + 1/24 = 1/4 ( 1/2) + 4 (1/3) + (1/2) + 1/24 = 1/8 + 4/3 +1/2 + 1/24 = ( 3 + 32 + 12 +1 ) / 24 = 48 / 24 = 2
