Hello guys, long time lurker, first time poster! You've all been a lot of help to me, this year and last year, and I really appreciate you taking time to help all of us!
Though, I never run out of questions, especially this year, I'm a private candidate with no teacher >.<
Could someone help with question 6 please? I got the dy/dx = 3cos(x) - 12 sin(x)cos^2(x) I just don't really know how to simplify it further..
Also question 5, I got stuck on this step : -e^(-y) = 1/2 e(2x) - 3/2
How can I ln it correctly?

Thanks in advance! And may God bless you all!
UPDATE : SOLVED CORRECTLY ( thanks sister ) WILL HELP IF NEEDED
