Well remember this:
When the signs are the same it is positive
When the signs are different make it negative
When you are subtracting a negative and positive, it is going to be like adding
for example:
-9 - 5 = -14
You just add 9 and 5 to get 14, the signs are different so it is going to be negative. ONLY WHEN YOU ARE SUBTRACTING NEGATIVES

Cos(arcsin(u)) = √(1 - u²)
_____
You want cos(α) where sin(α) = u.
You know that
cos(α)² + sin(α)² = 1
cos(α)² = 1 - sin(α)² = 1 - u²
cos(α) = √(1 - u²)
Idk but the web always helps me so you can ask that question online
