Calculus Level 5 Assessment

Ah, I'm pretty sure the answer was right... However, it said that was wrong. Was the question expecting the answer in degrees or... I'm not sure. I'm quite confident about the answer being right... Am I wrong? If so, any help in locating my mistake. Thanks in advance. I'd appreciate it.

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.

Since the value of $\cos 1$ is approximately 0.54, and all the other terms are less than 1, the product cannot be greater than 0.54, and thus neither can the limit. Hence $\sin 1 \approx 0.84$ is not correct. Check your reasoning again.

If you want help locating your mistake, you should be explaining the series of steps that you took. Right now, all that can be said is, "The product is not $\sin 1$ ."

If angles are given in degrees, then they will be stated as $1 ^ \circ$ . Generally, calculus tries to avoid degrees where possible.

Thanks! ~_~ I got it on the last try... Wew.

The answer is not $\sin 1$ . You are probably getting the product to telescope; if so, be careful, and check your calculations again. You should be close to the actual answer.

Thank you! I got it. :-0

Yes the ans is sin2. U probably have calculation mistake
