Therefore: .
I'll let you calculate the maximum and minimum.
Find the absolute minimum and absolute maximum values of f on the given interval.
f(t) = 3t + 3 cot(t/2),
[π/4, 7π/4]
Hey guys, I'm stuck on this and on my last attempt, please help me out here,
so the derivative is -3/2cos(t)csc^2(t/2)
Then I make it = 0, etc,etc.
My answers I got were pi/2, 3pi/2 but they were both wrong. Please help me out here, PLEASE!
