Using the expansions of cos(3x − x) and cos(3x + x), prove that
Rus_ich [418]
Cos (A - B) = cos A cos B + sin A sin B
cos (A + B) = cos A cos B - sin A sin B

cos 2x = cos (3x - x) = cos 3x cos x + sin 3x sin x
cos 4x = cos (3x + x) = cos 3x cos x - sin 3x sin x

1/2(cos 2x - cos 4x) = 1/2(cos 3x cos x + sin 3x sin x - cos 3x cos x + sin 3x sin x) = 1/2(2 sin 3x sin x) = sin 3x sin x.

What is the common ratio between successive terms in the sequence<br> 2,4,8,-16, 32, 64,
marysya [2.9K]

Answer: The sequence does not have common ratio.

Step-by-step explanation:

By definition, a sequence with a constant ratio (common ratio) between terms is called a "Geometric sequence". In order to find the common ratio, it is necessary to divide any term in the sequence by the previous term.

In this case, given the sequence:

2,4,8,-16, 32, 64,

We get:

4\div2=2\\\\8\div4=2\\\\-16\div8=-2\\\\32\div(-16)=-2\\\\64\div32=2

Since the ratios between the terms are not constant, we can conclude that <em>the sequence does not have common ratio.</em>
