Is this using JavaScript's eval()?

No — for safety, this uses a hand-written parser that only understands math syntax, not arbitrary code, avoiding the security risks of eval().

Does it support trigonometry in degrees?

No, sin/cos/tan expect radians, following standard mathematical and programming convention. Multiply degrees by π/180 to convert first.
