no it isn't. 2cos(x) is 2 multiplied by cos(x), cos (2x) is cos(2 multiplied by x) meaning 2x is the angle you're taking the cosine of. if you want to know what cos(2x) look up the double angle rule.

There are 52 colas and 26 lemon-lime sodas in the cooler. What is the ratio of colas to lemon-lime sodas?
sergejj [24]
Hi there.

If there are 26 lemon-lime sodas and 52 colas, then that means our ratio is going to be 52:26; however, this is not simplified as both of these are even numbers. To simplify, divide both of these numbers by 26.

26 / 26 = 1
52 / 26 = 2

Our new and simplified ratio of colas to lemon-lime sodas is going to be
2:1.

I hope this helps!
