Hello, My name is John and this is me a 54 year old engineer from the USA trying to help my son with his precalc homework! I am honored to to find a site in GB. Your engineering work is always the best!
The problem is 1+cos (y) / [ 1+ sec (y) ] and the answer is to be in sin or cos
The answer is cos (y) per the book
I tried 1/ [1+sec(y)] + cos(y)/ [1+sec(y)]
and then I get lost trying to rid of the + sign
