Alchen [17]

Answer:

Number of carbon atoms present in the sample are 391.

Step-by-step explanation:

We are given that,

Ratio of carbon to hydrogen atoms = 1 : 4

It is given that a sample of methane consists of 1564 hydrogen atoms.

Let the carbon atoms in the sample = x

So, we have the relation,

$\frac{Carbon}{Hydrogen}=\frac{1}{4}=\frac{x}{1564}$

i.e. $\frac{1}{4}=\frac{x}{1564}$

i.e. $x=\frac{1564}{4}}$

i.e. x= 391

Hence, the number of carbon atoms present in the sample are 391.

Express cos 5x in terms of sine multiples of x

Nataly_w [17]

<span>cos x = [ e^(ix) - e^(-ix) ] / 2i along with [ A - B ]^5 =

( A^5 - B^5) - 5 AB ( A^3 - B^3) + 10 A²B² (A - B )...A = e^(ix) , B = e^(-ix)

[ cos x ] ^5 = (1/32i) { [ e^(5ix) - e^(-5x) ] - 5 [ ( e^(3ix) - e^(-3ix) ] + 10 [ e^(ix) - e^(-ix) ] }

= ( 1 / 16 ) { cos 5x - 5 cos 3x + 10 cos x }.....much faster</span>
