Hi, We know:
Sin(a + b) = 2.Sin(a).Sin(b)
Then,
= 2Sin(a).Cos(b)/Cos(a).Cos(b)
Canceling Cos(b)
= 2Sin(a)/Cos(a)
As Tan(a) = Sin(a)/Cos(a)
Then we will stay:
= 2Tan(a)
Or
= Tan(a) + Tan(a)
There is anything wrong on the alternatives

➷ When it comes to dividing fractions, there is a rule you must now.
It's called Keep Flip Change.
I'll give you an example:

Keep the first fraction exactly as it is
Flip the second fraction upside down (switch the numerator and denominator around)
Change the sign to a multiplication.
This is how it should look:

Now you just multiply them as you normally would to get an answer of:
