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.

The equation of the conic section whose focus is at (-1,0) , directrix is the line 4x-3y+2=0 and eccentricity is (1/2)^1/2 is
 
 
Hello student, The eccentricity is given to be √½ < 1. Hence, the given conic section is ellipse. Now, the focus of the ellipse is F(-1, 0) and directrix is the line 4x-3y +...

The number of points (x,y) (where x and y both are perfect squares of integers) on the parabola y^2=px,p being a prime number, is ?
 
 
y 2 = px y = sqrt(px) Since x & y are perfect square integers, sqrt(x) is an integer. Since p is a prime no., sqrt(p) is an irrational no. The point which satisfies the given condition is...

If the pair of straight lines ax 2 + 2hxy – ay 2 = 0 and bx 2 + 2gxy – by 2 =0 be such that each bisect the angle between the other , then hg + ab = 0 ah + bg = 0 h 2 – ab = 0 ag + bh = 0
 
 
Hello student, The equation of the bisectors of angles between the lines ax 2 + 2hxy - ay 2 = 0 is (x 2 -y 2 )/(a-(-a)) = xy/h or hx 2 - 2axy – hy 2 = 0 ….…. (1) Also, bx...

solve mod x^2 +4x +3=x+1.
 
 
|x 2 +4x+3|=x+1, Now, the LHS changes at different values of x. x 2 +4x+3=(x+3)(x+1)=+ve for x -1 ...(i) while it is -ve for x between -3 and -1 ...(ii) So, for (i) we have x 2 +4x+3=x+1 on ...

Something is wrong with the greater than and less than symbol. I’m writing it in words: x 2 +4x+3=(x+3)(x+1)=+ve for when x is outside (-3,-1) i.e. less than -3 and greater than -1. Cheers!!

x 2 + 4x + 3 = x +1 x 2 + 3x +x + 3 = x + 1 (splitting the middle term) x(x+3) 1(x+3) = x + 1 (x+1)(x+3) = x+1 x+3 = x+1/x+1 x+3 = 1 x= 1-3= -2
