    Integrating a strange square root function

    Homework Statement Calculate the area under the curve for the following: f(x) = √x*√(−32 − x) and g(x) = √(−x2 − 32x) Homework Equations The Attempt at a Solution I've been trying to do partial integration since the functions f(x)=g(x)area are mirrored, so they are equal...

    Using Argument and DeMoivre's theory

    Hey, thanks so much for your reply! Using what you told me, I've managed to get to the next question, but I get stuck here. I'm not sure what I am doing wrong. Here's where I am so far: z6=1+i z=r1/6(cosΘ+isinΘ)1/6 z=6√2(cos(Θ/6)+isin(Θ/6)) z=6√2(cos(π/12)+isin(π/12)) and so...

    Using Argument and DeMoivre's theory

    Hello everyone, I'm having a bit of trouble with using the argument function with DeMoivres formula. I have the question: z8= 16 and am meant to find the solution using DeMoivre's formula (zn=rn(cosn(Θ) +isinn(Θ)) ). The problem is, I have no idea what an argument function is or how to find...
