Homework Statement
Use a graphing calculator to find [itex]\delta[/itex]
when
0<|x - [itex]\pi[/itex]/2|<[itex]\delta[/itex] and |sin(x) - 1|<0.2
Homework Equations
I don't think there are any other than the format of the previous information:
0<|x-a|<[itex]\delta[/itex] and |f(x)-L|<[itex]\epsilon[/itex]
The Attempt at a Solution
Okay, so I used the graphing calculator to graph sinx, y=1.2 and y=0.8
The thing is, L + ε turns out to be greater than 1, so I have something like this (i attached a picture).
For [itex]\delta[/itex] I got 0.61. I'm not sure if it's possible, because the line y=1.2 doesn't touch the graph of sinx. Is it possible?
Thank you!
