|
Which ratio of length does the Sine A give? |
It sines the length opposite the angle |
|
|
Which ratio of length does Cosine A give? |
It cosines the length adjacent the angle |

|
Explain inverse sine (0.5) |
If A=30° then SinA = 0.5. If we inverse sine it will give the value of the angle whose sine is (0.5). So inverse sine (0.5) will give us the value of A which is 30° |
