My name is Ethan, if thats what you're asking.
On this calculator, type in acos. Works the same as cos-1.
Hope this helps!
Little tip, -000000000 is still 0, so...
Well, if it is 3*(sqrt(3)/2), then it is 3*(sqrt(3)/2).
If it is (3*sqrt(3))/2, then it is (3*sqrt(3))/2.
Use this.
Hope that helps!
the greatest common factor is 1 because 13 is prime and 18/13 is not divisible without remainders.
Lucky... I still have a week to go until spring break. But otherwise my day's been going well.
