Question

Find the value of 2tan 45° + cos 30° - sin 60°

Answer 1

▪︎■ ANSWER ■▪︎

$\rightarrow\bf\underline{Solution}$

$2 \tan45°+ \cos30° - \sin60° \\ = 2 \times 1 + \frac{ \sqrt{3} }{2} - \frac{ \sqrt{3} }{2} \\ = 2 + 0 \\ = 2$

$\rightarrow\bf\underline{Always \: remember}$

• $\sin 0°=0$
• $\sin 90°=1$
• $\cos 0°=1$
• $\cos 90°=0$
• $\sin45°= \frac{1}{ \sqrt{2} }$
• $\cos45 ° = \frac{1}{ \sqrt{2} }$
• $\tan45°=1$
