Delta not equal to zero, and h^2<ab. It’s an ellipse.
Area is pi.a.b. But that gives 10pi.
But there a and b are the length of semi major and minor axes. Here a and b are just coefficients of x² and y²
I mixed them up why do I do this.
So there is no way to find out those lengths?
I tried to convert it into squares of two mutually perpendicular lines and then converting the lines into distance form, but unable to form the sum of two squares.
Isnt this tedious though?
Can you take SS bro? Can’t see unless login
Try writing it as a quadratic in x or y. The two roots of that quadratic will be two halves of the ellipse. Then we can integrate. Someone pls try if this works.
How did you understand this?
Always make it a rule to form quadratic in y only , in x it mess up badly always .
But how do we confirm that it gives two part of ellipse?
And do we do same for parabola and hyperbola?
I understood this
Which formula is this ? For area of any ellipse ?
How did you get that its an ellipse. Like in my book it says the same condition for empty set. Whats that then?
I have no idea bro
I have like a list of conditions in my notebook, and there it says this ones an ellipse.
To be more precise,
(coefficient of x^2).delta not equal to zero, and h^2<ab
Yeah. Ive seen those conditions but the problem is Amit M Agarwal gives the same but then in a side note says the condition of ellipse(without any mention of e) is for an empty set. What could that mean.
I don’t know, bro.. I’ll update if I find out something, though.
Can you post pics?
