Whoa! Have I forgotten my engineering Math?

I received this email from my Engineering classmate,

Mahesh, I was looking at the old math notes from my engineering and came across this question. You had also solved it. I hope you remember answers for this in case your daughter who is attending Engineering asks.

Find the positive value of  such that the area enclosed by the ellipse x^2/9 + y^2=1, the x-axis, and the line y=2x/3 is equal to the area in the first quadrant enclosed by the ellipse x^2/9 + y^2=1, the y-axis, and the line y=mx.

I am assuming it is a valid question and my friend is not pulling my leg. When I say pulling my leg it is not related to my Math skills (which was very good in student days) but he is testing my memory.  I did not even attempt to solve the problem as I was blank as a clean slate.

In engineering days we had to “prove” few facts in Math. My friends who were very creative would scribble the workings and confidently end their answer with “Therefore LHS = RHS” (left hand side = right hand side). By any stretch of imagination LHS was not resembling RHS. My friends knew it, my teachers knew it. Anyway, all my friends are well settled now. Math had no bearing on their future.

Akhilesh Yadav

Talking about my engineering days, my college SJCE has been in news lately as Uttar Pradesh’s rising politician Akhilesh Yadav is from SJCE (Environmental Engineering, 1994 batch).

If he performs well we all will say “He is from OUR college”, until then safe to say “he is from SJCE”.
