The opposite of what?

lots

EP and i have interpreted this question differently.

I think that he has interpreted that the second leg goes half the speed of the first leg and he has found his answer.

This may well be the intended interpretation

BUT

I interpret it that the second leg takes twice as long and how far it is is irrelevant.

If the first leg cost $1.20

and the second leg takes twice as long then I think the cost will be 60c

tan^2(x) = tan x what are the possible values of x in 0=<x<360

\(tan^2x-tanx=0\\ tanx(tanx-1)=0\\ tanx=0\qquad or \qquad tanx-1=0\\ x=0,\; 180,\;360,\;\;or\;\; tanx=1\\ x=0, \;180,\;360,\;\;or\;\; x=45, \;225\\ x=0^\circ \;\;45^\circ,\;\;\;180^\circ, \;\;225^\circ \qquad 0 \le x<360 \)

Well if you have the original graph, the inverse is its reflection across the line y=x

The notation makes no sense. 

I like it!  I just sent it to a friend in Algeria :)

You have taken the entertainment of the world very seriously I see :))

Thanks Alan,

More brain food for me  :)))
