Nishant bhaiyya check this?~

would somebody like to answer to #16????

Q2

equation given: y2=x2-a2/x2

so x=0 ie y axis is obviously one asymptote

rewriting the equation in terms of x : x2=a2/1-y2

so y=±1 are asmptotes

so in total three asymptotes

Q1

when x=1 the y→∞ is easily observed from the equation

plotting not necessary for both the curves

subash bhai pehle #16 ka answer bata de na

11
Subash ·

that is all very deep manipal (ill try)

but the problem is simple enough without bringing in graphs

asymptotes can be found without graphs

Subash ·

x=±10 i dont see what is your doubt beyond that?

Mani Pal Singh ·

i agree with ur method but please answer this 1

solve this 1
if

x2=102
so x will be equal to ????

Subash ·

ive replied for that

x=±10

ok.....but thanks to u........i had actually told to myself that i wont plot this.......but when u said that this plotting was out of our reach..then i got the inspiration and sudden burst of energy to solve this one...

arre why further discusson is going on on this topic???????

answer is 2 asymptotes......i checked in the answer key too..........

so dont worry .my soln is OK.....[1][1]

what about x=0 isnt that an asymptote?

y=1,-1 are others

why x=0 is an asymptote?????????????

eureka123 ·

think properly..
here is definition of asymptote

An asymptote is a straight line at a finite distance from origin to which a given curve approaches indefinitely nearer as we recede towards infinite distance[1][1]

i agree wid u eureka...it wont touch in infinity

sir do u recognise the 2nd curve which is given in #1
can u help us with it????

voldy ·

for Q2 ) the asymptote is x=0

Mani Pal Singh ·

x jab negative hoga to kya y bhi negative hoga[7][7][7]

r u sure about the 3rd and the 4th quadrants[12][12]

MAY BE 2ND ONE COULD BE BETTER EXPLAINED BY KAYMANT ,NISHANT OR PROPHET SIR

BECAUSE I HAD ASKED MY TEACHER TO FIND THE AREA UNDER THESE TYPE OF CURVES AND HE TOLD ME THAT THESE TYPE OF CURVES R STANDARD

THEY ALSO HAVE SOME NAMES 4 THEM

THEY READ ABOUT THESE THINGS IN THE ENGINEERING

it wont be that dificult .....

we have plotted descartes vala graph in graph of day.......

11
Mani Pal Singh ·

no they r not difficult but they r standard .
I wont say it is impossible to solve 4 us
But the actual thing in the question and its beauty could be explained by professionals better

so i leave this 1 4 them[1][108]

as u wish......

ok i am trying to plot 2nd one........

Domain
x2-a2≥0
&x≠0
=> x ε (-∞,-a]U[a,∞)

Range :
y2x2-x2+a2=0
=> x2(y2-1)+a2=0
since x real => D≥0
=> -4a2(y2-1)≥0
=>yε [-1,1]
range=> [-1,1]

Mani Pal Singh ·

i think u solved ur own problem
good use of algebra

but i was saying about the plotting thing..............
