How do you do the first one on the calculator?
since cscØ = 1/sinØ
csc (2π/5) = 1/sin(2π/5)
How did you get the second one correct but miss the first one ?
csc (2π/5) = 1/sin(2π/5)
How did you get the second one correct but miss the first one ?
I think it's because I didn't put in the pi correctly.
All whole numbers are rational numbers.
