again see your graph in 3rd quadrant

I have doubt on that

thats what I did ......
why mine is wrong then ??

Isnt this one also same as here ??
http://targetiit.com/iit-jee-forum/posts/daily-graph-1-08-09-11530.html

it simplfies to tan({x}{y})=1
=>{x}{y}=nπ+π4=m where m is variable of course...

now for diff values of m there will be rectangular hyperbolas..

zero

Manish Shankar ·

eureka

{x}{y}=nπ+π/4

ans {x}{y}<1 so what is the value of n

24
eureka123 ·

yep karna is rite..graph only this part only

24
eureka123 ·

for n=0

24
eureka123 ·

it will be in 1 and 3rd quad only becoz tan gioves positive value in htese only

24

kk..

Manish Shankar ·

yeah its kind of repeated

m in your solution sound of no use.

can you simplify it further

Some discontinuity too.....

I ma working on quadrants...
