dheer_07 -> the solution has many steps , ..the main point is integration of log | sec theta | d ( theta ) .. Integrate this one by breaking sec into cos ..u will get minus of integration 1/2 log cos theta d ( theta) within the limits 0 to pie / 4 .

No the answer is ( pie )square / 4 + pie ln 2 -( pie/2) ln 2 ..you must have missed some 2 somewhere .And "

sandeepramesh" yes, u are right ..this question is abt a type of IIT JEE subjective pattern ....it is not right to put up this question in board level exam .

yeah , but he is the only guy here in Kolkata who has solved and got this answer .I called him when I reached home ...it was around 3 pm , he was probably having some ice cream somewhere .., there only he took the back of the question paper ans started solving ......but right now he called me and said that the question is not at all difficult , but it is a perfect 6 marks question .

yes it is 100 percent right ..but heay "sandeepramesh " ...check my previous posts ...I dint mean that the answer can come in 2 steps ..I means the expression
2 theta2 sec2theta d (theta)

can be brought in 2 steps only by putting x = tan theta . My friend came to this expression by breaking 2 tan inverses and then bringing one of them to sin and the other one to tan .What the hell was he thinking ...anyways , that expression is the key to answer of this question . As I said before , cbse is going to give marks ( at least 4 ) to the students who have got that expression .
