inequality!!!!! true or false?

[Nanie]

I'm in Calculus... but the professor gave us this excercise and he said that it is Pre-Calculus....

But....I really need help with this excercise....

Previously I just evaluate p =2 and theta = (?/4)

But the professor made a correction of p values...(above) and I don't know what to do!

Thanks and sorry for my english!

Your images did not line up properly

Is your problem

\(\displaystyle [\cos (\theta)]^p \, \le \, \cos (p \cdot \theta)\)

or

\(\displaystyle [\cos (\theta)]^p \, \le \, \cos (p ^\theta)\)

or

\(\displaystyle [\cos (\theta ^p)] \, \le \, \cos (p \cdot \theta)\)

or

\(\displaystyle [\cos (\theta ^p)] \, \le \, \cos (p ^\theta)\)

or something else.....
