Write the trigonometric expression <br> Cos (arcsin (u))<br> As an algebraic expression in u

makvit [3.9K]

When we use arcsine, we are finding the angle while giving the trigonometric ratio.

Arcsin(u) = theta can be rewritten as:

sin(theta) = u

Sine is opposite over hypotenuse, so u/1 means that the side opposite to theta (the y value) is u, and the hypotenuse is 1.

We can use Pythagorean Theorem to find the adjacent (x value).

1^2 - u^2 = x^2

x = sqrt(1-u^2)

Back to the original question, we are trying to find cos(arcsin(u)). We just solved all the sides for our triangle using arcsin(u). Now we need to do cos(u).

Cosine is adjacent over hypotenuse.

So our answer is sqrt(1-u^2)/1

Or just sqrt(1-u^2)

Which best describe a vector

ANEK [815]

Answer:

Vectors are used to represent physical magnitudes that have an associated address.For example,if we want to represent the displacement of an object,it is not enough to describe only the distance as 10 meters, it is also necessary to describe in which direction the displacement occurred,for example,30°towards the northeast.

Hope this helps:)
