                                        x2+y2+2gx+2fy+c=0

condition for orthogonal,
2*g*10=c+4
perpendicular fron center to x=2 is radius..
f2=22g
put g=-x and f=-y
hence,y2=-22x

if x^2+y^2+2x+1=0,then the value of x^31+y^35 ?
 
 
x^2 +2x+1 + y^2 can be written as (x+1)^2 + y^2= 0. Only possible when x = -1 & y= 0. So -1 is your answer. Thanks Bharat Bajaj IIT Delhi askiitians faculty

If the orthocentre of a triangle is at (4,5) and the centroid is at (3,3), where is the circumcentre located? Answer is (2.5,2). Please explain.
 
 
so.. centroid is dividing Orhtocentre and circumcentre in 2:1 internally use section formula if the circumcentre is (x, y) for X-coordinate: 3 = (4*1 + 2* x)/ 3 ….....(1) 9 =(4*1 + 2*...

Why is equation (1) not a polynomial equation and equation (2) not a polynomial in y? (1) dy/dx + sin(dy/dx) = 0 (2) (dy/dx) 2 +(dy/dx) - sin 2 y = 0
 
 
Being a equation and a polynomial equation is very different. Functions like sinx, lnx, e x are not considered polynomial quations. They are transcental functions.
