Ex 7.10, 20 The value of โซ_((โ ๐)/2)^(๐/2)โใ(๐ฅ^3+๐ฅ ๐๐๐ ๐ฅ+tan^5โกใ๐ฅ+1ใ ) ๐๐ฅใ (A) 0 (B) 2 (C) ๐ (D) 1 โซ_((โ๐)/2)^(๐/2)โใ (๐ฅ^3+๐ฅ ๐๐๐ ๐ฅ+tan^5โกใ๐ฅ+1ใ ) ๐๐ฅใ Thus, our equation becomes โซ_((โ ๐)/2)^(๐/2)โใ(๐ฅ^3+๐ฅ ๐๐๐ ๐ฅ+tan^5โกใ๐ฅ+1ใ ) ๐๐ฅใ = โซ_0^(๐/2)โใ0 ๐๐ฅ+โซ_0^(๐/2)โใ0 ๐๐ฅ+โซ_0^(๐/2)โใ0 ๐๐ฅ+๐โซ_๐^(๐ /๐)โ๐ ๐ใใใ = 2โซ_0^(๐/2)โ๐๐ฅ = 2 [๐ฅ]_0^(๐/2) = 2(๐/2โ0) =๐ Thus, correct option is C
