Question

evaluate 2tan^2 45°+cos^2 30°/sin^2 60°
plz answer this question if anyone

Answer 1

Answer:

The value of given expression is 2.

Step-by-step explanation

we have to evaluate

2\tan^2 45^{\circ}+\cos^2 30^{\circ}-\sin^2 60^{\circ}

\tan 45^{\circ}=1

\cos 30^{\circ}=\frac{\sqrt3}{2}

\sin 60^{\circ}=\frac{\sqrt3}{2}

2\tan^2 45^{\circ}+\cos^2 30^{\circ}-\sin^2 60^{\circ}

2(1)^2+(\frac{\sqrt3}{2})^2-(\frac{\sqrt3}{2})^2

2+\frac{3}{4}-\frac{3}{4}

2

The value of given expression is 2.
