I got 6.33% but apparently it's 3.2%

A bucket contains 11 letters: 5 vowels and 6 consonants. How many 7 letter words can you make if you use 3 vowels and 4 consonants? I think the ans should be 5C3x6C4x7! but they say this is wrong at college. Any help is appreciated. Thank you Mentor note: Changed thread title to agree with...

Yeah. I know the formula. I did 1/(z-1)^2 but didn't come out as partial fractions.

All it says is that "C is any simple closed contour around both z = 1 and z = i"

How would you integrate sin(z)/(z-1)^2 using Cauchy's Integral Formula? 1 is in C. Cheers

Grant Keady won't be happy.

My electrodynamics lecturer was talking about how potentials are arbitrary and that's why we have different gauges. I'm not too sure about how potentials can be arbitrary. Up to a constant? How? Cheers,

G'day, If you're given a vector q and have that del x p=q (i.e curl(p)=q), how would you find p? Also for divergences. cheers

Similar situation here. I've nearly finished the science part of engineering/science. After this year I have 2 years to go. I am sick to death of uni and would rather leave after this year and apply for a job as a mechanical engineer. Do you reckon this'll work? My science majors are maths and...
