im having trouble with these two, finding the global max/min, i just dont understand how to do it...
g(t) = t/(t^2+5)
Determine the global extrema of g(t) on the interval 1 ≤ t ≤ 8.
g(t) has a global minimum at t =
g(t) has a global maximum at t =
f(theta) = sin^2(theta)-cos(theta)
Determine the global extrema of f(θ) on the interval 0 ≤ θ ≤ pi.
f(θ) has a global maximum at θ =
f(θ) has a global minimum at θ =
