This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Assuming that the angles are in degrees, the result is zero since cos(90)=0\cos (90)=0.

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

Simplify (xa)(xb)(xc)(xz) (x-a)(x-b)(x-c) \cdots (x-z) .

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

hello, the result is very ugly 1.14893012274526133709121721740219091292398251438476437266×1046-1.14893012274526133709121721740219091292398251438476437266\times10^{-46}
