Negative Power of a trigonometric function

409 Views Asked by At

I was doing a question in which I had to compute the left hand limit of $(\sin X)^{x}$. So in my solution booklet it is given that the left hand limit doesn't exist. When I graphed it on Desmos, the part on the -ve $X$ axis was missing, at least near $0$. Why does this happen? I mean, the sine of a negative number, however small it is should be a negative number, and negative numbers can be raised to exponents of negative numbers too. Then what's the problem here?
