Hi ganesh;








In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.

Re: Objective Type

hi ganesh,

I interpreted Q2 the same way as bobbym: what is the angle at the circumference when the chord is a diameter?

Don't know why; it's just something in the wording that pushes me that way.
