Question

How do you evaluate the expression csc(0.8)?

a) csc(0.8) = 1/sin(0.8)
b) csc(0.8) = 1/cos(0.8)
c) csc(0.8) = 1/tan(0.8)
d) csc(0.8) = sin(0.8)

Answer 1

The correct way to evaluate csc(0.8) is by taking the reciprocal of the sine of 0.8, which means csc(0.8) = 1/sin(0.8).

Step-by-step explanation:

To evaluate the expression csc(0.8), we need to understand the definition of the cosecant function in terms of the sine function. The cosecant of an angle is the reciprocal of the sine of that angle. Therefore, csc(0.8) = 1/sin(0.8), which makes option a) the correct answer.To evaluate the expression csc(0.8), we need to understand that csc(x) is equal to 1/sin(x). So, the correct option is a) csc(0.8) = 1/sin(0.8). This means that to find csc(0.8), we need to find the value of sin(0.8) first and then take its reciprocal.
