How do you find the answer from the sendon to last step on sine then to last step on sine?

$\frac{\sqrt2}2\times\frac{\sqrt3}2+-\frac{\sqrt2}2\times\frac12\\ =\frac{\sqrt2}4\times\sqrt3-\frac{\sqrt2}4\times1\\ =\frac{\sqrt2}4[\sqrt3-1]$

4. oldrin.bataku

Your result is equivalent, merely a simplified form of the one they listed.
