Apps->Solve other solutions

[averagejoje]

I am trying to find the solution to
0 = 20 + 15*sin(pi*x/6) - 4 - 2^(0.1*x^2) , where x >= 0.

I enter the equation
y = 20 + 15*sin(pi*x/6) - 4 - 2^(0.1*x^2)
into Apps->Solve.

If I press the Plot button, I can see multiple solutions where y = 0.

If I press the Num button, enter y=0 and press the Solve soft key, I get only 1 of the solutions (and not the one I want).

I get the same solution that I don't want if I use Toolbox->Solve->Solve.

1) How do I get the other solutions to the equation?
2) On Plot, how do I find precisely where the graph crosses the x-axis?

Thanks.

Touch on function with finger. Touch Menu - Fcn - 4 Root and you see the x value of the next root on the bottom of the screen.
