## Homework Statement

The joint probability density function of X and Y is given by

f(x,y)=c*

**1**(|y|<x<1) 1 is the indicator function

-Find c

-Find the marginal densities of X and Y

-Find the means, variances and the covariance

-Find conditional densities, means and variances of X given Y and of Y given X

## Homework Equations

3. The Attempt at a Solution [/B]

The thing is I don't know how to deal with the |y| to find the limits of integration

For example to find c :

1=c∫∫f(x,y) dx dy

y goes from -∞ to 1

But for x ?

Thanks
