Sounds like homework. What are your own thoughts on the
problem?

v = dx/dt
cos(pi/2) = cos(90 degrees) = 0.
cos(pi/2).v = dy/dt = 0.

xi = (x-vt)/sqrt(1- 0.v²/c²) = (x-vt)/1
tau = (t-vx/c²)/sqrt(1-v²/c²)
= (t-v²t/c²)/sqrt(1-v²/c²)
= t(1-v²/c²)/sqrt(1-v²/c²)
= t*sqrt(1-v²/c²)
= t*sqrt(1-0.v²/c²)
= t*sqrt(1)
= t
Einstein did not know the difference between speed and velocity.

Androcles does not understand the meaning of any of the
variables in any of the equations.

Brilliant :-)

Exercises for "vector":
E1: say hello to Androcles, our Village Idiot.
E2: explain the main error to the idiot.
E3: explain to the idiot how he could have saved himself a lot of typing.
E4 for "vector": find the additional deliberate error, specially
introduced to recover the Galilean transformation that the
idiot doesn't understand either.

There is no difference between the two reference frames in the direction
perpendicular to the relative velocity vector.

Some other idiots (Dirty Van of the Motel, etc.) still try to figure
out the square root:
