How do you calculate #cos^-1(0.7253)#?

Question:

How do you calculate #cos^-1(0.7253)#?

Answers

#43^@51 + k360^@#
#316^@49 + k360^@#

Explanation:

Find arccos (0.7253)
Use calculator and trig unit circle -->
cos x = 0.7253 ---> arc #x = +- 43^@51 + k360^@#
Since the arc #- 43^@51# is co-terminal to arc #(360 - 43.51 = 316^@49)#, there for, the general answers are:
#43^@51 + k360^@#
#316^@49 + k360^@#
