ज्ञात करे
` int_(-1)^(1) |x| dx`

लिखित उत्तर

Verified by Experts


अब ` int _(-1)^(1) |x| dx = int_(-1)^(0) |x| dx + int _(0)^(1) dx = int_(-1)^(0)-x dx + int _(0)^(1) x dx`
` [ :' " जब " -1 lt x lt 0, |x| = -x " तथा जब " 0 lt x lt 1, |x | = x] `
` = - [ (x^(2))/2]_(-1)^(0) + [ (x^(2))/2]_(0)^(1)= - (0-1/2 )+(1/2 -0)=1`
