The value of $\frac{\sin 30^{\circ} \sin 60^{\circ}}{\cos 60^{\circ} \cos 30^{\circ}}-\tan 45^{\circ}$ is: |
5 0 $\frac{2-\sqrt{2}}{2}$ 2 |
0 |
\(\frac{sin30º. sin60º}{cos60º.cos30º}\) - tan45º { using sinA = cosB Iff A + B = 90º } = \(\frac{sin30º. sin60º}{sin30º.sin60º}\) - tan45º = \(\frac{1}{1}\) - 1 = 1 |
