Graph of integral

[lrdheat]

Thanks!

Interestingly, here's some comparisons for int(abs(sin(x)))=4

Actual answer is 2pi=~6.28318530718

In solve Prime comes up with 6.28318305852
In Graph where I used AREA for the integral minus 4, root came up with 6.2831849099, more accurate than the solve app answer.

My CASIO fx-9860GII in solve finds 6.2831844

In graph mode, finding x for y=4, after 6+ minutes produces 6.283145931, less accurate than the solve app.
