• Sure, sounds like fun!﻿
• Hey Serena, do you want to come to San Diego with me for a party?﻿
• This party is so much fun. I have a question though, I am working on something and one question is find the solution to the square root of cotangent of 60 degrees squared plus 1. ﻿Do you know how to solve it?
• Hmmm....No idea. Let's go downstairs to the party and see if anyone knows. Let me warn you ahead of time we may have to go over to the store because no one may know the answer and the guy at the store is really smart.﻿
• ﻿Yes I do know how to solve that problem.
• Excuse me, we have a question...how to do solve the square root of the cotangent of 60 degrees squared plus 1?﻿
• So first you ﻿take the tangent of 60 degrees which is the square root of 3. Then you do the opposite since you're looking for cotangent which is the square root of 3 over 3.
• Finally you add 1 and you get the answer as 2 square root of 3 over 3.﻿
• Thank you so much!﻿
