If I want to find the general solution of
how would I go about doing this?
What would be a possible method that you could use to solve this question
Thanks if you can help me
Note that if we have a solution. So find all the where is any odd integer is one set of solutions.
Now assume , we can divide by it to get
Now change out to something more convenient and continue
(instead of this thing about considering whether cosine is zero or not, the standard way would be to bring the cosine on the right to the left, factor it out and set each factor to zero)
