Value cant understand using trig

[Ryan Rigdon]

I have listed my problem below and i am having trouble with exactly where cot^(-1)(0) exists on the unit circle.

I know that cot = 1/(tan t). Would cot^(-1) = tan t = (sin t)/(cos t)?

Anyway here is the problem.

STUCK RIGHT HERE cot^(-1)(0).

I have listed my problem below and i am having trouble with exactly where cot^(-1)(0) exists on the unit circle.

I am not sure what the question really is.
But \(\displaystyle \text{arccot}(0)=\frac{\pi}{2}.\)

The range of \(\displaystyle y=\text{arccot}(x)\) is \(\displaystyle (0,\pi)\).

Thanx pka i was able to finish my problem. Even though i got timed out. I had to do a new one here it is. Thought you might like to see it.
