Answer:
0.5* sin(x)
Step-by-step explanation:
As well known sin (2A)= 2sin(A)*cos(A)
As in our case A=x/2 => cos(x/2*sin(x/2)=1/2*sin(x)=0.5*sin(x)
For this case we must indicate an expression equivalent to:

For properties of powers we have to:

So, the above expression can be rewritten as:

Thus, the resulting expression is: 
Answer:

Option D
L=k/r^2,
r^2 is the denominator cause L varies inversely with the square of distance
