Trig Questions
1. Write the algebraic expression which shows Cos((ArcSin(4/X)),
2. Angle If Csc(Θ)=15/4?
2.  what quadrant is it in, find the sin(Θ), Sin(Θ), Tan(90degΘ), Tan(Θ), csc(Θ), Sec(Θ+360deg), Thanks

These are rather simple if you make drawings or sketches.
For instance on the first, if sin is 4/x
then the hypotenuse is x, the opposite side is 4, and the adjacaent side is sqrt(x^24). So now what is the cosine?
You can do this. We will be happy to critique your thinking.
