Re: 10 second questions
Hi bobbym,
The solutions #4508 and #4509 are correct. Brilliant!
Given sec θ = 13/12, find
#4510. cosec θ
#4511. cot θ

In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.
