plot all the points on the graph where this is true...

Not very difficult... may be a bit differnt

but last yr we solved tons of such graphs..

but sir
sin{x}+cos{x}=0
means sin{x} and cos{x} are of opposite signs
how is this possible
when
0≤{x},{y}<1

@ eureka... that much is sure..

@Arshad.. You have almost given the correct answer without stating it explicitly..

Arshad ~Died~ ·

this situation is only when possible sinx=-1/√2
and cosx=1/√2
but such a situation cant be achieved with fractional part of x.......
sir i am very confused.........pls explain.....

Arshad you are confused because you are giving the right answer [3]

Lokesh Verma ·

or in other words..

Null Set?

Arshad ~Died~ ·

yup
null set
cant be plotted.......
how stupid have i been.........!!!!!(to say the least)

Arshad ~Died~ ·

i had assumed that as it was under the daily graph section therefore maybe a graph was possible..........its always wrong to assume things.....
