[input]7![/input]

first customer can be placed at 7 different positions in the line.

second customer can be placed at (7-1)=6 different positions in the line. (because first customer already occupies a position).

and so on.

that's: 7 (possibilities first customer) * 6(possibilities second customer) * 5*4*3*2 * 1 (possibility last customer) = 1*2*3*4*5*6*7 = 7!

[input]asin( 300*sin(84) / 100 )[/input]
this is a complex solution.

[input]300*sin(84) / 100[/input]
the argument of asin(..) is 2.98356568610481.

[input]plot( sin(x), x=-360..360 )[/input]
sin(..) has a result between -1 and 1.

asin is the inverse of sin, so an argument outside of -1..1 (here 2.98356568610481) has to result in some "complex" result. (which is in this case really a complex number)
