Use parametric equation , to find equation of normal, and then find its distance from 0,0 . Maximise it
I did that only and the answer matches it as well. But how is this logically correct? As the perpendicular drawn should give the shortest distance right?
Generally to find shortest distance distance between a curve and a point we draw a perpendicular. But here we have to find the max distance....
Ok , so it should be maximum perpendicular Distance, because of we think like that, max distance will not be finite
Why perpendicular distance? The question doesn't mention the word 'perpendicular'. It just says find the max distance
U got a point so why isn't the answer infinite?
Yeah, it means perpendicular distance only . Many a times it's not mentioned
Ohk got it thanks bro
Got Q7 and Q8
@Lalit_Kumar4 , what is the answer for Q9
Q-9 Use SS1=T^2 and then angle b/w these pair of straight lines 60 degrres
Yeah , I have also used this concept but messed up with calculation. Too much calculation with variables.
Yeah searching for shorter method
@Lalit_Kumar4 , For 10 if you will be able to understand it
For Q-9 you could use tanx=m1-m2/1+m1m2
You can find difference and product of slope with the help of tangent equation in slope form (makjng it quadration in m)
Ohk got it thanks @Udit_Takkar
Btw u mean to say tan(60) =m1-m2/1+m1m2 right?
I didn't understand any of it @Gaurav_Singh11. Can anyone explain what they did?
Sorry , to disappoint you but I also do not understand what they did over there. I am not getting any idea how to solve Q 10? Anyone please try it
@pratyaksh_tyagi , @Sourav_Madanpuri
Plz try Q6 and Q10
