JEE Main2018MathematicsArea Under CurvesActual
If the area of the region bounded by the curves, y = x 2 , y = 1 x and the lines y = 0 and x = t t > 1 is 1 sq . unit , then t is equal to
Options
- Ae 2 3
- Be 3 2
- C3 2
- D4 3
Correct answer
A. e 2 3
Step-by-step solution
Area = ∫ 0 1 x 2 d x + ∫ 1 t 1 x d x = 1 ⇒ 1 3 + ln t = 1 ⇒ t = e 2 3
