Show that the perpendiculars falling from any point of the st.line 2x+11y=5 upon the two st. lines 24x+7y=20 and 4x-3y=2 are equal to each other.
 
 
solution: given L1 :24x+7y=20 ; slope M1 = -24/7 L2 ;4x-3y=2 ; slope M2= 4/3 and L3 :2x+11y=5 ; slope M3= -2/11 ifperpendiculars falling from any point from the line L3 to L1 and L2 areequal...

How does find the slope of a circle. Please give me an easy method which works all the time. Thanks
 
 
Dear student, We know that atany pointP having the coordinates (x,y)on the unit circle satisfies the relation Hence, we get that Now we can use the usual parameterization of the circle, i.e....

If the lines joining origin and point of intersection of curves ax 2 +2hxy+by 2 +2gx=0 and a1x 2 +2h1xy+b1y 2 +2g1x=0 are mutually perpendicular,then prove that- g(a1+b1)=g1(a+b)
 
 
a petty question on homogenization of equation. ax 2 +2hxy+by 2 +2gx(1)=0 ...1 a1x 2 +2h1xy+b1y 2 = -2g1x ...2 a1x 2 +2h1xy+b1y 2 /(-2g1x)=1 ...3 now replacing 1 in eq 1 by a1x 2 +2h1xy+b1y...

Hi Student We know using trigonometry sin = p/h and cos = b/h and using identity sin 2 + cos 2 =1 p 2 /h 2 +b 2 /h 2 =1 p 2 + b 2 = h 2 (Hence proved)
