Can you find the definite integral with unknown boundaries on this calculator? Does anyone know? (E.g. from 2 to m) Thanks!

When calculating the integral of a function that crosses the x-axis, it considers the area under the x-axis as negative. Is there any way to change this setting on the calculator to consider the negative area as positive? Thanks

Somethings not right. I somehow got 1.77E2. Does anyone know what I'm doing wrong?

I see you are pressing “window” not “alpha” as you said.
