Hi everyone - I'm sure there's somebody here who can help with such a trivial question.
It's not a homework question before that's assumed - it's from a past exam paper, which I'm using for revision, sans answers.
It asks to describe, in the complex plane, the image of:
|z - 1| \leq 1...
Sorry if this is in the wrong section, I wasn't sure where to post it.
Can anyone help me - I need to solve the following differential equation and find the values of c and B.
> k is given as -98.3146.
> v = 55 when t = 9
> v = 50 when t = 10
k(v^2) + B = m.(dv/dt)
Am I right in...
