Homework Equations
modulus, argument, roots.
The Attempt at a Solution
For the 1st question I've gotten the modulus, the principal argument and the abs. of z^1/4 which was something like 1.5335 I believe. The only thing I am not understanding with regards to this question is the final part, where it is asking for the smallest argument, 2nd smallest, 2nd largest and largest in that ascending order.
I've tried several things but none of them have worked to give me a proper answer. I'm probably missing something really stupid like "Just divide it by x to find smallest, add x to find largest, take away x to find second smallest" or some standard format like that.
2nd question I got these as my answers
1: e^(3x)
2: -3y
3: -(i*arg(-2+4i))/3 + ln(abs(-2+4i))/3
yet they don't seem to be the correct answers, I think I must be leaving out a step in the 2nd one.
