Solution:Let I=∫0π xsinx1+cos2xdxThen,⇒ I=∫0π (π−x)sin(π−x)1−cos2(π−x)dx⇒ I=∫0π (π−x)sinx1+cos2xdxAdding (i) and (ii), we get2π=π∫0π sinx1+cos2xdx⇒2I=−π∫1−1 11+t2dt, where t=cosx⇒2I=−πtan−1t1−1=−π−π4−π4=π22⇒ I=π24 Related content Nucleus Diagram for Class 9 Neuron Diagram Class 9 Human Heart Diagram Class 10 CBSE Class 7 Science Chapter 1 Nutrition in Plants MCQ Questions with Answers CBSE Class 9 English Worksheet – The Road not Taken 50+ GK Questions and Answers for Class 8 “Kabir Ki Sakhiyan” MCQ Questions for Class 9 Hindi with Answers Kshitij, Kritika, Sparsh, Sanchayan Bhag 1 CBSE Class 7 English Honeycomb Chapter 1 Three Questions MCQ Questions with Answers CBSE Class 9 English Beehive Book Poem 1 The Road Not Taken MCQ Questions with Answers MCQs Questions with Answers for Class 9 English Chapter 1 The Fun They Had
