Answer:
Step-by-step explanation:
1 .1 ( .1 repeating) =
Let x=0.1
Then 10x = 1.1111...
= 10 + 0.(1)
= 10+ x.
So, 9x=10 and lastly, x=
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
