Due to increase in the value of eggs by 20 percent, two eggs started getting less at Rs. 24. The current price per dozen of eggs.

The value of $$ {3sin30°-4sin^{3}30°}$$

The value of $$ {2(1-sin^{2}θ)}+{2(1-cos^{2}θ)}$$. 

$$ {3sin60°-4sin^{3}60°=?}$$

$$ {3tan^{2}30°}-{4\over 3}{sin^{2}60°}- {1\over2}{cosec^{2}45°}+{4\over3}{sin^{2}90°=?}$$
