Sketch Re(z^4). ie:sketch real part of z^4
I tried to do the arithmetic and I think Re(z^4)=x^4 - 6x^2*y^2 + y^4
Hi everyone thanks for checking I was so conserned with my arithmetic i forgot the rest my apologies. I need to sketch {z element complex numbers such that Re(z^4)>0 and |z-1|<2}
I know how to sketch the |z-1|<2 part and i assume the part I want is where the 2 overlap i just not sure how to sketch x^4-6x^2*y^2 +y^4
