You also missed squaring the secant function.chwala said:Yeah I noticed that...thanks slight error, I left out ##dx##
I think you are looking at the wrong page, check my post number ##3##SammyS said:You also missed squaring the secant function.
No. My replies are referring to Post # 2.chwala said:I think you are looking at the wrong page, check my post number ##3##
