Q84.The values of ∫ 1+2x −π2 (1) π (2) π 4 8 (3) π (4) 4π 2 JEE Main 2018 (08 Apr) JEE Main Previous Year Paper

What This Question Tests

The question assesses the application of definite integral properties, specifically the King's property for symmetric limits, combined with trigonometric identities to simplify and evaluate the integral.

Concepts Tested

Properties of definite integrals (even/odd functions)King's property (∫f(x)dx = ∫f(a+b-x)dx)Trigonometric identities

Formulas Used

∫ₐᵇ f(x)dx = ∫ₐᵇ f(a+b-x)dx

∫₋ₐᵃ f(x)dx = 2∫₀ᵃ f(x)dx if f(x) is even

∫₋ₐᵃ f(x)dx = 0 if f(x) is odd
