Advanced Graphing ?

[Snorre]

Hello lrdhead,

Am I right, that you want for any arbitrary area a to find an x(a), so that
\[ a=\int_0^x \max(\sin\theta,\cos\theta)d\theta \]

If so, I haven't found a solution you might want, since I couldn't get "Advanced Graphing" to plot anything involving areas/integrals.

You could plot that in "Function" app (patience!), and then look at the numeric table. But this is driven by the step of x, not a(x).

Another way is using the "Solver" app.
1st: enter your problem; 2nd: solve x for a given a; 3rd: plot
           

Sorry, that's not the nice tabular solution (a vs. x(a)) you may expect
