Use the appropriate identity to find the indicated function

Use the appropriate identity to find the indicated function value. Rationalize the denominator, if applicable. If the given value is a decimal, round your answer to three decimal places. csc theta, given that sin theta=1/7 7 1/7 -7 1/7

Solution

sin theta = 1/7
cosec theta = 1/ sin theta
therefore,
csc theta = 1 / 1/7 = 7
