Answer 1

To find:-

• value of 2 tan² 45° +cos² 30°+sin² 60°

Solution:-

as we know

1. tan 45°=1
2. cos 30° = $\frac{√3}{2}$
3. sin 60°= $\frac{√3}{2}$

Now put value in 2 tan² 45° +cos² 30°+sin² 60°

=> 2(1)²+$\frac{√3}{2}$ ² +$\frac{√3}{2}$ ²

=>2+$\frac{3}{4}$+$\frac{3}{4}$

=>2+$\frac{6}{4}$

=> 2+$\frac{3}{2}$

=>$\frac{7}{2}$
