                Use a calculator to evaluate the trigonometric function. Round to four decimal places. Make sure that your calculator is in the correct angle mode.
1) csc 2pi/5
1.3213?
2) sec 0.7
1.3075?

    since cscØ = 1/sinØ
csc (2π/5) = 1/sin(2π/5)
How did you get the second one correct but miss the first one ?
