y = 0 * ∞

y=(c/∞)*∞

where c is a real number

now we get

y=c

So, zero times infinity is an undefined real number. This is the definition of undefined. Therefore, zero times infinity is undefined.

If the limiting values are zero and infinity then the limiting value of their product is in indeterminate form. It can be a real number or doesn't exist. Its value can be found out by doing operations on the expressions which are getting multiplied.
