If f(x)= {(a|x|+x^2-2( sin |x|)( cos |x|))/x, x ≠ 0; b, x=0} is continuous at x=0, then a+b is equal to
If $\displaystyle f(x)=\left\{\begin{array}{cc}\frac{a|x|+x^2-2(\sin |x|)(\cos |x|)}{x} & , x \neq 0 \\ b & , x=0\end{array}\right.$ is continuous at $\displaystyle x=0$, then $\displaystyle a+b$ is equal to
