h(t)=cot t
intervals: pie/4, 3pie/4
totally lost on this one... cant find a formula to plug in the intervals. Help :/ Thanks.

Question

anonymous · Answer

are you supposed to graph?

anonymous · Answer

$$\cot t = 1/\tan t$$
So, cotangent is just an inverse of tangent. Hope this helps.

anonymous · Answer

not "inverse" but "reciprocal"

anonymous · Answer

:-) Can be. I am not so sure about the terminology.

anonymous · Answer

with functions "inverse" means "inverse function" so the inverse of 

$$f(x)=x+1$$ is 
$$f^{-1}(x)=x-1$$ not 
$$\frac{1}{x-1}$$ which is the reciprocal

anonymous · Answer

no, no graphing I just have to plug the intervals in and come up with the answer. answer in the book is, -4/pie
how do I denote pie on this site?

anonymous · Answer

$$h(t)=\cot t$$
itervals given, $$\pi/4, 3\pi/4$$
