so I've been studying principia mathematica by whitehead and russell.
it seems like its all principia and no mathematica. it just feels like I am taking philosophy logic again.
does it get more mathy later?
any books that will help me with math proofs?
my question relates to the axisymmetrical ring vortex.
i know that vorticity must remain constant within a tube, (helmholtz vortex theorem 2)
so does that mean that the vortex lines on the outside of the ring are longer (spinning faster)
than the ones on the inside?
also is that what makes...
Homework Statement
i got to find the complex amplitude
i know that w = 50Hz
displacement was 30mm at time 0
and -14mm at time 12ms
Homework Equations
(displacement) = Acos(phase constant)cos(wt) - Asin(phase constant)sin(wt)
The Attempt at a Solution
so I've tried plugging...
