Can radius be negative under the x axis
WebAlthough it sounds tempting, area cannot be negative. When a function dips below the x-axis, the space between the function and the x-axis should be treated the same way as if it were above the x-axis. Because there is no absolute value sign, both II and III are wrong as they subtract area from themselves. 3 comments ( 45 votes) Upvote Downvote WebJul 19, 2014 · On the other hand, the definite integral of a negative function (that is a function under the x -axis) gives a negative area. This is. ∫ a b f ( x) d x ≤ 0. for a function such that f ( x) ≤ 0 when a < x < b. Now, the problem comes when you have a function that goes for a while over the x -axis, and for another while under it.
