That's OK.
This is a harder test.

Consider the complex exponential e^j*theta. Using Euler's identity we may expand this term as e^j*theta=cos(theta)+jsin(theta)
This result indicates that we may express the continuous time sinusoidal signal x(t)=Acos(wt+f) as the real part of the complex exponential signal Be^jwt (w is the angle like theta) where B itself a complex quantity defined by B=Ae^i*f (f another angle)
that is we may write
Acos(wt+f)=Re{Be^jwt}

What colour is it?

pink?

A train from New York travels west at 75mph.  30 minutes later a train from Los Angeles goes east at 90mph.  The train from New York makes a 2 hour stop in St Louis.  The train from Los Angeles makes a 45 minute stop in Albuquerque.  Both trains are due to arrive in Dallas.  What is the New York train driver's name?

It was a runaway so there was no driver.

His name is Buck. Every engineer has the name Buck in all the films I've seen.
