Convolution of h(n) & x(n) can anyone please help me with finding Convolution for following problem .....

1) $h(n) = \delta[\sin(1 + |n|)]\quad \text{and}\quad x(n) = \sin(n^2)$

2) $h(n) = \delta[\sin(2\pi n/N)] \quad \text{and}\quad x(n) = n^2$ where $N$ is odd.
HINT:

I assume that $n$ is an integer and that we're talking about discrete-time signals. You need to simplify the expressions for $h(n)$ by noting that $\delta(n)=1$ for $n=0$ and zero otherwise. So, for which values of $n$ does $\sin(1+|n|)$ equal zero, and for which values of $n$ does $\sin(2\pi n/N)$ equal zero?
