for the second one, factor out, and combine like terms to get your answer
I got a complete different answer from any of the choices, can anyone lead me to the right direction as to get an answer to this?
I ended up with xe^6x/cos(x+6y)-1/6, any help would be appreciated you thank :]
same as this one,
I ended up with e^x(x^2-2x+6)+e^x(2x-2)
