Question

Cos (300) + Sin (135°) - tan (120°)​

Answer 1

$\Large{\underline{\underline{\sf{Given:}}}}$

• $\cos(300) + \sin(135 ) - \tan(120)$

$\Large{\underline{\underline{\sf{Required\; Solution:}}}}$

$\cos(90 \times 3 + 30) + \sin(90 \times 2 - 45) - \tan(90 \times 2 - 60)$

$- \sin(30) + \sin(45) - ( - \tan(60) )$

$- \sin(30) + \sin(45) + \tan(60)$

$- \frac{1}{2} + \frac{1}{ \sqrt{2} } + \sqrt{3}$

Done :)
