Question

If c^2+s^2=1 what does c+s=

Answer 1

I don't have a lot of info to go off of to properly solve the question, however I think I may be able to help. If you are trying to solve using the Quadratic Formula:

_______________________________________________________

Solve the rational equation by combining expressions and isolating the variable c.

`c=\sqrt{(1+s)(1-s)`

`c=-√((1+s)(1-s))`
