Homework Statement
Three functions are defined as follows:
f:x> cos x for the domain 0< (or equal to) x < (or equal to) 180
g:x> sin x for the domain 0< (or equal to) x < (or equal to) 90
h:x>tan x for the domain p< (or equal to) x < (or equal to) q
Find the range of f.
-1<(or equal to) x < (or equal to) 1 (correct?)
Given that the range of h is the same as the range of g, find a value of p and a value of q.
this is the one i don't quite understand, i got p = 0, q= 90, is that right?
if the domain is the same therefore the range is the same, yes?
