I did q1,q2,q3,q4 (series) I did up to proving the second to last inequality and I used the 2nd to last inequality to prove the RHS of the last inequality.q5) complete although I had to come back to part a), q6 most'y complete, i went wrong proving the integral=12root3/5. But the last part I did fine using this result.
q7) I found the stationary point although miscalculated the y-cordinates, made a logical i think guess to the value of m that had to be stated. x=m
skipped to the graph sketch, and blanked out on finding the m for mx+1. Got to 5/16 but blanked there, so hopefully ill get error carried forward onto the sketch and some method marks on the mx+1.
I think it was a hard paper,it wasn't anything like before especially the integrals and series question
