    Here you go , if I have any mistake tell me =) For part three you just have to sub in any root from the two roots you got in part 1 in z^6 and expand and simplify, you will reach -64

    Yeah I treated 3^x as a term, so I subtracted 3^x from 9(3^x) to get 8^x

    I think that would be a straight vertical line at 1 on an Argand diagram, since it says Real of z greater than 1, if you need to shade you'll have to shade on the area more than 1, that would be to the right of the vertical line. I might be wrong though, if I am correct me please.

    I find chemistry the hardest, I find physics, math, mechanics and biology much easier then chemistry xD

    Physics: Post your doubts here!

    According to lenz's law, emf tends to oppose the change causing it, so here, sketch will just have opposite peaks, and when current is constant, no emf on sketch, since no emf is induced when there is no change

    Here you go, if you have any more doubts tell me :) Justification : Drop down a perpendicular to get AB or AC in terms of r and use simple trigonometry , then cross out r^2 and simplify , change (Costheta)^2 and 2sintheta.costheta into their identities . Then make cos2theta the subject :)...
