The solution for proving the identity is as follows:
sin(2A) = sin(A + A)
As sin(a + b) = sinacosb + sinbcosa,
<span>sin(A + A) = sinAcosA + sinAcosA
</span>
<span>Therefore, sin(2A) = 2sinAcosA

D = rt
We are given the rate r to be 15 mph.
We are given the time (in hours) to be 3.5.
We need to find D.
D = (15)(3.5)
D = 52.5 miles.
Did you follow?
