Answers : (1)


by using the formula

tanA=modulas of (m1-m2)/(1+m1m2)

where A=45 and m1=+1

we can fine m2 from that we get two values

so we get two lines.

using the three lines we find the oint of intersections.

from the area formula we get the area covered by the triangle.

If the angle between the two straight lines represented by 2x 2 +5xy+3y 2 +7y-98=0 is tan -1 m then find m.
required angle is tan -1 {2squareroot(h 2 -ab)/a+b}=tan -1 {2squareroot(25/4-6)/9} =tan -1 (1/9) so m=1/9 Thanks & Regards Sunil Raikwar askIITians Faculty

Show that all the chords of the curve 3x 2 -y 2 -2x+4y=0 which subtend a right angle at the origin pass through a fixed point. Find that point.
Let y=mx + c be the equation of chord Homogenize the equation of curve 3x 2 -y 2 -2x+4y=0 by putting 1= (y-mx)/c Equation becomes 3x 2 -y 2 -2x(y-mx)/c+4y(y-mx)/c=0 Homogenization gives the...
