Inputting 3 piecewise functions in one f(x)???
I am trying to do a Solid of Revolution about the x-axis with 3 functions creating my enclosed area, like this:
However when I put it into geobra
f(x) = If[0.22 ≤ x ≤ 1.087, ℯ^x / 2, If[1.087 ≤ x ≤ 1.794, acos(x - 1),If[0.22 ≤ x ≤ 1.794, 1 - sqrt(3 / 4 - (x - 1)²)]]]
It only prints out the top two functions and not the bottom one. I need all three in one f(x) because I'm using this template: https://www.geogebra.org/m/HPTaQb4w
Here's what I'm getting in GeoBra:
The last function, the half-circle is not printing out. This is for a Calc project.
And here's what it should look like:
