Question

if y(ln3)=2 and y=(e^2x) - 1/(e^2x) + C, what is C?

Answer 1

okay let y=2 and x=ln3, sub these values in to get C

Answer 2

I know ho to do that but what is e^2ln3 ?

Answer 3

e^(2ln3)=e^(ln3^2)=e^(ln9)=9

Answer 4

ok so does e^lnx always equal x?

Answer 5

correct

Answer 6

thank you very much!
