Webb9 sep. 2015 · 360 - 330 = 30, so we are subtracting 30 degrees from 360 to get the sin inverse, 330. Since we are subtracting from 360, the ratio will remain sin, and because it is in the 4th quadrant, the sin will be negative. Therefore, our answer is −sin(30), or − 1 2. Sorry if this seems confusing, this is how I learnt it. Answer link. WebbSin 30° = \ (\sqrt {\frac {1} {4}}\) = ½ Sin 45° = \ (\sqrt {\frac {2} {4}}\) = 1/√ 2 Sin 60° = \ (\sqrt {\frac {3} {4}}\) = √3/2 Sin 90° = \ (\sqrt {\frac {4} {4}}\) = 1 Sin 45 in Radians & Degrees You can check the values from the table below: Sin …
