really wasted for me haha, at the last few minutes i coudnt even differentiate 13b) properly - i though d/dx e^x - e^-x was equal to zero, forgot about the negative sign for the 2nd term, sigh. worse thing was that qn was worth 22 marks i probably will get a single digit from that qn :(

i was happy that i managed to prove the integration qn (i think it was qn 10) although it did waste me quite a bit of time cus of the substitution back and forth
