Hey guys- These are out of the 4u Fitzpatrick book, ex 37(a) If you haven't had a go at them you probably should try taking a look at them some time soon because they take aaagggesss to see.. (or it could've just been me). Well, anyway, there are three that I can't get out, any help would be...

Yup, I'm stuck, yet again: (i) State a condition for z, w, v (all complex) to form the vertices of an equilateral triangle on the Argand Diagram. (ii) If z = 1 + 3i, find a complex number w, so that z, w and the origin O form the vertices of an equilateral triangle. Thanks for taking a...

Hey, i'm stuck on a few integration questions, any help would be very nice... :) Find the indefinite integrals of: 1. (x^2 + 1)^(1/2) 2. cotx / [ln(esinx)] 3. [1/ (2x - x^2)^1/2] Thanks in advance!

Okay guys, it's a pretty stupid question, because of the not being allowed to use the double angle rule, but I just cannot see any other way of doing it! If you can come up with a solution, it would be absolutely wonderful! Thanks in advance. Prove that: tan[2@] + cot@ = sec[2@] *...

Hey- not sure if this is in the syllabus any more, but: Use the result (cos@ + isin@)^n = e^(i@) to prove DeMoivre's theorem, namely (cos@ + isin@)^n = cos(n@) + isin(n@).

One of the dot points I have to research on for an assessment is: - Gather and process information from secondary sources to trace developments in understanding and describing acid/base reactions. ...and I, and the majority of my grade don't really know what it's actually asking us to do-...
