Form a family of straight lines passing through the point of intersection oflx+my+n=0 andpx+qy+r=0. (px+qy+r)+µ(lx+my+n)=0 Find the angle betweenlx+my+n=0 andpx+qy+r=0 and equate it to the angle...
Hey...its very easy. See, we know that for a triangle with vertices (x1,y1), (x2,y2) and (x3,y3) the centroid (h,k) is given as h = (x1+x2+x3)/3 and k = (y1+y2+y3)/3. Here we have all the three...
if you draw yhe diagram, and put C1,C2 the centre of circle with r=5. c3 the centre of circle of r=3. Since circle(c3) touch the both circle C 3 C 1 =C 3 C 1 -->C3 lies on perp. bisector of C1C2. let...
how you can say that they intersect at y=x , its for sure that they are symmmetric but i think its only a special case that they intersect at y=x.
it is a squre with line X=+a,-a Y=+a,-a
The lines 3x – 4y =0 and x+y=0 intersect each other at (0,0). Also the line 3x + 2y = 0 passes through (0,0) and is perpendicular to the third line 2x – 3y=7 . Therefore it passes through ORTHOCENTRE...
The answer is 6 units. I’ll give you hints. Dr’s of the line is Therefore, PN = sqrt[(3-1) So N = (1,0,1) Satisfying this point on the plane gives u=-4 General point on this line is..(u/2 +3, u+4,...
What’s wrong with this question? See, you might have been confused about in what manner are the axes rotated whether clockwise or anticlockwise, but the options are eliminating the doubt. Try to just...
The answer is ay – bx + 2a = 0 See, we have given a line x+y=2 Also it is rotated about the point where it cuts the y-axis [i.e.,(0,-2)]. So for the new line, we have a point (0,-2). Its given that...
