    Two scholarships at once??!

    Pretty sure that if the equity scholarship is $6000 or more you can't have both. I have a similar issue being offered an entry scholarship ($6000 for one year) and an access scholarship ($6000 p.a. for the length of my degree).

    Mooorre Integration by Substitution

    Okay so third and hopefully last dumb integration question: ∫ √(x/(1-x) dx {with limits between 1/2 and 0}, letting x = cos<sup>2</sup>@ Undoubtedly I'm doing something stupid again. Please and thanks! :)

    More Integration by Substitution

    Could someone please show me why the answer to this: ∫ (sinx)/(√(1 + 2cosx)) dx {with limits pi/2 and 0} using the substitution y = 1 + 2cosx is √3 - 1? I keep getting a quarter of this answer?? Thanks! (Sorry I don't know how to make my limits pretty)

    Integration by Substitution

    I'm stuck on this integration question: Find ∫ dx / (25 + x<sup>2</sup>)<sup>3/2</sup> by letting x = 5tan@ I keep getting 1/25 sin(tan<sup>-1</sup>(x/5)) + C but the answers give 1/25 x/√(25 + x<sup>2</sup>) + C. Are these answers equivalent (if so could someone please show me why) or am I...

    Simple Trig. Question

    Okie so when I simplify (tan2x)/(1-tan22x) I get (1/2)tan4x. The answers tell me I should get (1/4)tan4x. Am i doing something wrong? Please and thankyou! :)

    Complex numbers

    Sorry this is probably a silly question. How do I prove that there are always two square roots of a non-zero complex number? I get four square roots! How do you know when to only take the positive number when you have +/- a square root? If that makes sense...? Thank you! :)
