h(t)=cot t , itervals given, π/4,3π/4 finally got the equation written out, took me and while to figure it out, sorry. book answer is 4/pi but I have no idea how to set this up

Best ResponseYou've already chosen the best response.0what does it mean "the answer is \[\frac{4}{\pi}\]? there is no question, just a definition of a function \[h(t)=\cot(t)\]

Best ResponseYou've already chosen the best response.0Sorry to jump in after 7months on this question, but I'm having trouble understanding how you factored out the cot for the top. I'm getting stuck at \[\cot(3\pi/4)−\cot(\pi/4)\] How did you arrive at 1 and 1 for the top? I plugged it into my calculator and it came up something like 0.01something.

Best ResponseYou've already chosen the best response.2i believe that 7 months ago that was a joke :) pi/4 radians is equivalent to 45 degrees. the tangent of an angle is the slope of the line that the radius makes with the positive x axis. the cotangent is just the inverse of the tangent. dw:1346155666663:dw tan(pi/4) = n/n = 1, the inverse of 1 is: 1 when we have three pi/4 s, we end up with a 135 degree angle; dw:1346155817540:dw as such; tan(3pi/4) = n/n = 1, the inverse is: 1 1  (1) = 2

Best ResponseYou've already chosen the best response.0Ah! Thank you so much! I got the beginning bit, and the last bit, but not the actual cot bit. My prof skipped the precal review, and in retrospect I knew I should've looked it over before classes started. Thanks for going into such depth, really helps. ^_^
