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 you wrote urgent , i tried to solve it as soon as i saw it , hope it helps, plz tell if my ans is correct or not, you can change my answer into other forms using trigonometry, tell if you have any problem, in second last step, one root is rejected as u can not be negative. reply as soon as possible!!!!

Thank you for your helping. I guess my answer was the same of yours. But then I wrote urgent because I just want to check if my answer is correct or not. Thank you so much. I appreciate your answer.
