Locus of R (1 Viewer)

[chriscity1]

I got y=-a cause R is on the directrix

 

[Rorix]

unfortuantely, tanget at p and q dont meet at right angles, it's OP and OQwhich are perpendicular

 

[jesshika]

that's what i got as well because pq = -1

is that right tho ??

 

[CharlieB]

it wasnt the directrix

 

[withoutaface]

that's what i got as well because pq = -1

is that right tho ??

pq=-4 i think

 

[fantasia]

no pq does not equal -1.

the gradient of OP = p/2
gradient of OQ = q/2

therefore OP times OQ = pq/4 = -1 (since they are perpendicular)
therefore pq = -4

I had that at first.... but then i got pq=-4.....cos the 90 degree was between Lines P and Q at O

i doubt it asked for directrix???? @#^%!@^#!#@%^
