Gaurav Seth 6 years, 11 months ago

We know that, the semi latus-rectum of a parabola is the harmonic mean between the segments of any focal chord of the parabola.

Given that, b and c are lengths of the segments of any focal chord of the parabola y²=4ax

So, Let l is the length of semi-latus rectum of the parabola.

Then,1/b+1/c=2/l

⇒ l=2bc/(b+c)

Hence, length of latus-rectum=2bc/(b+c)

find the equation of the line passing through the mid point of 1,2 and 3,-1 and parallel to the line 3x-4y+5=0

Posted by Šïmmï Vërmä 6 years, 11 months ago

CBSE > Class 11 > Mathematics

Ram Kushwah 6 years, 11 months ago

mid point of (1,2 and (3,-1) is

(2,1/2)

The equation of line will be like

3x-4y=k( as the lines are parallel)

or 3x2-4x1/2=k

k=6-2=4

so eqn is

3x-4y=4 or 3x-4y-4=0
