Everyone would be happy and smiling... until the grade boundaries come out.

Doe anybody know whether or not one can sketch Polar coordinates with the fx 9750? If so, how?

Is this the Fx 9750 gii?

Of all my exams this year, Hitler has only felt the need to react to M2. Hoping it can stay that way for the last two!

Both of my further maths modules so far (FP3 and M2) have been pretty bloody dreadful.

Quick check, for Newton-Raphson errors is this example correct?

e3/(e2)^2 = e4/(e3)^2

Sorry about the formatting.

It was easy apart from 7 and proof by induction probably very high boundaries.

What did people get as their line of symmetry?

line of symmetry pi/10, was an okay paper apart from the induction, i wrote it out twice but forgot to cross one out so may lose all marks there

Got pi/10. Sin is symmetrical about pi/2

Really good paper I thought. Hopefully not extremely high boundaries.

You used a set of unit width rectangles lying below the curve to evaluate an upper bound (2) for that sum using an integral. You weren't expected to find the exact value of the sum which is what WolframAlpha has evaluated.
