Hello, i have just finished one of my A level papers, i think i aced it except for the first question, and any fluffy mistakes i made.
e^x +3e^-x = 4
solve it!
after the customery after test discussion there seemed to be a differant answer for each student, and in one special case 4.
Can anybody please solve this question for me, as its bugging me pretty badly.
Thank you
