(This problem uses a TI89 calculator)
Find the largest and smallest values of the following function on their given intervals:
y=(cos x)^x
[1.5, 4.75]
This is what I put in the calculator (home screen):
fMin((cos(x))^x,x I 1.5 < x < 4.75
(I = "with" symbol, < is less than or equal to)
I keep getting the error message that says domain error. Help please?
Thanks!
