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, from the given options, should be A TRIANGLE. I got it by eliminating the rest of the options. P.S:- I have checked for the first three options. From them, i haven’t got the answer so I...
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...
Yes, Length of intercept made by circle on a line = 2(r 2 - p 2 ) 1/2 where r = radius of circle, p = perpendicular distance from centre to the line
Since a,b,c are in AP let a = A - d, b = A, c = A + d ax+by+c = A( x+ y+ 1) – d(x – 1) = 0 The point of intersection of the given family of lines is the point of intersection of the lines x+y+1=0 and...
my friend please refer my questions posted under ANALYTICAL GEOMETRY
Solve the 2 side eqns to get the point of intersection. Check if this point lies on the diagonals whose eqn is given. If yes, then this diagonal emerges from the point if intersection. If no, then the...
Find the eqn of focal chord using the condition that the focal chord passes through the focus(a,0) as well as(at^2 , 2at) by using the two point form of the straight line. Now, find the point of...
hii [(a)(b)(c)] = a.(bxc) mod( a ) mod( b ) mod( c )sin( thetha )cos( alpha ) This value is given equal to mod(a) mod(b) mod(c) Hence sin(thetha)cos(alpha) = 1 thetha = pi/2 alpha = zero hence b.c = 0...
Hi student, we have rectangular hyperbola xy=c 2 take a general point on this in parametric P(ct, c/t) Now tangent at point P is T=0 xy 1 + yx 1 = 2c 2 So in parametric x(c/t) + y(ct) = 2c 2 x/t + ty...
Find the angle between the 2 lines and the point of intersection. Use this angle to find the slope of the angle bisector by adding/subtracting the angle from the slopes of the 2 lines. You have the...
Hi student, 2x+6y + 9 =0 and x-3y + 2 =0 so a 1 a 2 + b 1 b 2 = 2*1 + 6*(-3) = 2 – 18 = -16 <0 So negative sign will give me obtuse angle bisector So Now you can simplify the above Concept is...
