The limit of Cos X as x approaches one using the formal definition.
Given epsilon values of .1, .001, .00001
The Attempt at a Solution
Spent all period in physics calc trying to solve this using the formal definition.
Since there is no way to manipulate abs(cosx-.5403)<epsilon
I proceeded to make my delta = the epsilon values and plug into the equation.
None of the answers were working correctly. Any help would be greatly appreciated because i have a feeling that im missing something here.
