Here's a similar problem that I believe most of you have seen.

Simplify \( (x-a)(x-b)(x-c) \cdots (x-z) \).

0

if the angles are in degrees then answer is obviously 0. but i don't think they meant that. i think angles are in radians , then the answer would be approx: -1.14893 * 10^-46

i have used degree values here don't use radians....

haroun M 's answer is correct,think easily because it's so much easy

Yes but one hour later than I posted...

approx -1.14893 * 10^-46

how???

maybe he take it in radian.

hello, the result is very ugly \(-1.14893012274526133709121721740219091292398251438476437266\times10^{-46}\)
