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?

1. I get 1.05146

2. ok

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 ?

I think it's because I didn't put in the pi correctly.

All whole numbers are rational numbers.

To evaluate trigonometric functions, you can use a scientific calculator that has trigonometric functions available. Here's how you can evaluate the given trigonometric functions:

1) csc(2π/5):
a) Ensure that your calculator is in the correct angle mode, which is typically either in degrees or radians.
b) Input the value of (2π/5) into the calculator and find the cosecant of that angle.
c) Round the result to four decimal places.

The correct answer for csc(2π/5) rounded to four decimal places is approximately 1.1759.

2) sec(0.7):
a) Confirm that your calculator is in the correct angle mode.
b) Enter the value of 0.7 into the calculator and calculate the secant of that angle.
c) Round the answer to four decimal places.

The correct result for sec(0.7) rounded to four decimal places is approximately 1.4424.

Please note that the specific values may vary slightly depending on the calculator and rounding method used.
