The value of sin60° cos30° - cos60° sin30° is : |
$\frac{1}{2}$ $\frac{1}{\sqrt{2}}$ 1 $\frac{\sqrt{3}}{2}$ |
$\frac{1}{2}$ |
sin60° cos30° - cos60° sin30° = \(\frac{√3 }{2}\) × \(\frac{√3 }{2}\) - \(\frac{1 }{2}\) × \(\frac{1 }{2}\) = \(\frac{3 }{4}\) - \(\frac{1 }{4}\) = \(\frac{2 }{4}\) = \(\frac{1 }{2}\) |
