they have not proven the n=k+1 case, they have just proven the assumption
@ExtremelyBoredUserQ3
I'm sure there's an easier way (for sure) but this was the most apparent from the start (and its 11 pm I don't want to think rn haha). The main idea is that I tan'd both sides of the claims and I would use the tan(A+B) or tan(A-B) formula to produce a simpler expression. The last part is just algebra and its just trying to find a way to make it like the RHS expression so its just factoring.
I legit slept halfway through and then I realised I didn't even finish working so I rushed it.. but yes ExtremelyTiredUser is more fitting nowadays. If only I could change usernames.@ExtremelyBoredUser
Given your post that is why I named these files like this.
There is the word "hence" so you may consider using (ii).Q6iii
Yesterday in my sleep I had a very good idea to finish the question.
On the LHS use the fact thatand then slowly close up the present as you repeat that process three times.
