If m_(1),m_(2) are the slopes of tangents to the ellipse S=0 drawn from (x_(1),y_(1)) then m_(1)+m_(2)

If m_1 and m_2 are slope of tangents from a point (1, 4) on 16x^2 - 25y^2 = 400 , then the point from which the tangents drawn on hyperbola have slope |m_1| and |m_2| and positive intercept on y-axis, is: (A) (-7, -4) (B) (7, 4) (C) (-4, -7) (D) (4, 7)

If m_1,m_2 are the slopes of the two tangents that are drawn from (2,3) to the parabola y^2=4x , then the value of 1/m_1+1/m_2 is

If m_1,m_2 are the slopes of the two tangents that are drawn from (2,3) to the parabola y^2=4x , then the value of 1/m_1+1/m_2 is

If m be the slope of common tangent of y = x^2 - x + 1 and y = x^2 – 3x + 1 . Then m is equal to

The slope of common tangents to x^(2)+4y^(2)=4 and x^(2)+y^(2)=3 is m ,then m^(2) is

A : The sum and product of the slopes of the tangents to the parabola y^(2)=8x drawn form the point (-2,3) are -3/2,-1 . R : If m_(1),m_(2) are the slopes of the tangents of the parabola y^(2) =4ax through P (x_(1),y_(1)) then m_(1)+m_(2)=y_(1)//x_(1),m_(1)m_(2)=a//x_(1) .
