I don't understand the last step of mathematics in senior one. How did you get in? The problem before step 1: ln is known in △ABC.
ln(sinA+sinB)= lnsinA+lnsinB-ln(sin b-sinA)

Transposition ln (Sina+sinb)+ln (sinb-Sina) = lnsina+lnsinb.

Using logarithmic algorithm

ln(sinA+sinB)(sin b-sinA)= ln sinA sinB

So (sinA+sinB)(sinB-sinA)= sina sinB.

SinB Party-Sina Party = Sina SinB
