```        if any question like this
x=.........,    y=............
then how to find relation b/w x and y
```
7 years ago

```							Those questions are somewhat difficult to solve but its not impossible    If x and y r given in the same parameters then one has to eliminate that parameter to get relation between x and y     For instance : if x = cos (@) Y = sin ( @ )  Then v have to eliminate the @   In this case the relation is too easy cos^2(@)+sin^2(@)=1 I.e x^2+y^2=1  Thats the required relation  This is just basic kind of problem   Where others can be like  x=t^2+2t+1 and y = t^2 -2t +1 This one requires examining  Which gives x = (t+1)^2 and  y = (t-1)^2 That gives root(x)-root(y)=2 Which is required answer    The more models u practice the more skilled u become and u can find the ans giving method
