I am having trouble using my calculator to solve sec, csc and cot values.
Find sec0 when cos is 97.977
How do you come up with the answer -7.20587921?
===============
Most calculators, all I've ever seen, do sine, cosine and tangent.
---
You have to use sec = 1/cos, csc = 1/sin and cot = 1/tan.
======================
Find sec0 when cos is 97.977
-------------
Not sure what you meant there. The cos has a max of 1
If you mean sec(97.977) degs:
sec(97.977) = 1/cos(97.977)
=~ -7.205879213
Must be it, matches your answer.
