what can you say about the conics? can u give me an example of conics?
Circle, ellipse, hyperbola, parabola are examples of conics Conics usually have an equation of degree 2... There are many forms of equation but right now just stick to the most basic one
tnx #robinfr93. can you give me the standard form of any type of conics?
parabola: Ax2 + Dx + Ey = 0 circle: x2 + y2 + Dx + Ey + F = 0 ellipse: Ax2 + Cy2 + Dx + Ey + F = 0 hyperbola: Ax2 – Cy2 + Dx + Ey + F = 0
what is the purpose of getting the asymptotes of the hyperbola?
#Jedai17 provided you the general form of the conics.. The standard forms are these.. Circles : x^2 + y^2 = r (r is the radius) Ellipse: x^2/a^2+ y^2/b^2 = 1 for horizontal axis and x^2/b^2+y^2/ a^2 = 1 for vertical axis (a is one of the co-ordinate of major axis and b a co-ordinate of minor axis) Parabola: y = x^2
Umm bata_17. Can I ask you a personal question which grade are you in??
Btw general form are little advanced formulas to deal with Ill say keep it simple!! :)
sure @robinfr93. do i look too young? i'm already 2nd year college
Hey @robinfr93 , slight mistake in there... *Circles* x^2 + y^2 = r^2 ... in place of *r*...
hahahhaa!! yes you do!! @saloniiigupta95 thanx for the answer back there, I for got to square two there so was getting the wrong answer!! yeah ryt!! Thanx for pointing that out!! Another Typo!! Sigh!! :P well I'll say if you don't have a solid foundation in graphing functions and asymptotes and all, try reading Precalculus by John W Coburn. It'll Clear all your doubts adn will give you an understanding on how to use all these stuff in rela life!!
The "general" equation of a circle is: x2 + y2 + Dx + Ey + F = 0 The "center-radius" form of the equation is: (x – h)2 + (y – k)2 = r2 another information about circle. @saloniiigupta95 your equation in circle is correct
thanks for the informations :)
nah I'm pretty sure thats also standard equation. general equation of a circle is of the form ax^2 + by^2 + hxy + 2gx + 2fy + c =o
with centeres (-g,-f) and radius (g^2 + f^2 - c)^1/2
oops sorry theres no xy term.. sorry!!
man its just not my day I guess!! :'(
but still thats the general form!! and what you typed was the standard form!!
ahh ok thank you so much :)
