\mathrm{CO}_2 has 2 oxygens for every carbon. \mathrm{CO} will contribute one of each for every molecule. You then have to have an even multiple of \mathrm{CO} molecules to not end up with an odd number of oxygens.

So if you take 2\mathrm{CO}, you should end up with 2 carbons on the RHS. 2\mathrm{CO}_2 then has 4 oxygens. 2 of them are already accounted for, so you just need one \mathrm O_2 to balance out the reaction.

1\mathrm O_2+2\mathrm{CO}\Rightarrow2\mathrm{CO}_2

O2 + 2CO = 2CO2. That should be it

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)
