The cosine of what angle gives 1?

$\cos(\theta) = 1$  What is $\theta$?

anonymous · Answer

I got 99 degrees but I feel like that's wrong? I tried to do cos(1), but then again, I could be approaching figuring that out the wrong way?! @tkhunny

Seriously?  You should spend a little more time reading the owners manual on your calculator.  You may wish to be sure you know the difference between Radians and Degrees.

Why would you try cos(1)?  The problem clearly states $\cos(\theta) = 1$.  Please don't invent your own problems.  Solve the ones you have been given.

$\cos(\theta) = 1 \longrightarrow \theta = 0$
Okay, what are all those other things at zero (0)?

Using zero for all of the others I get 0 degrees, 0 radians, 0 for sin, 0 for tan, undefined for csc, 1 for sec, and undefined for cot?
