If you guys dont mind answering a small question...mod[z^2-(conjugate of z)^2] is greater than or equal to 16 eventually you would get to mod(4xy)=>16. according to the cambridge textbook this is mod(xy)=>4 but isnt this just xy=>4 i dont just why it is also xy is less than or equal to 4?

OMG SPIRALFLEX I LOVE YOU!

When proving that triangles ABC are ADB are similar it is clear since both contain a right angle and share the angle BAD. We have known shown that these are similar since they are equiangular and it follows of course that the final angle is also equal due to the interior angle sum of a triangle...

Re: 2012 HSC MX2 Marathon damn...i cant get the second part to that question ^

HSC and Preliminary Physics is for you more than it is for someone like me. Why? Because it definitely is NOT an mathematically orientated as a physics course would be in university. The maths gets as difficult as applying the quadratic formula which you should have done in year 10. It is much...

That?

I got x=0,2pi,pi/5,3pi/5,pi,7pi/5,9pi/5 which equate to x=0,360,36,108,180,252,324 in degrees
