Finding the inverse of a function.

Question

sin(alpha) = 0.195946 implies alpha = 
tan(beta) = 0.818491 implies beta =
sec(theta) = 2.5913 implies theta =

 

Find the following to one decimal place. Show me how you to get the answer

Answer 1

sin(alpha) = 0.195946 implies alpha = arcsin(0.195946)
tan(beta) = 0.818491 implies beta = arctan(0.818491)
sec(theta) = 2.5913 implies theta =

 

To find the arcsin(0.195946) Use the second function sin on your calculator followed by (0.195946)

or shift sin (0.195946).

If you want your answer in degrees , make sure that the mode is set to degrees.
