bird that was perched atop a 15 ½ foot tree dives down six feet to a branch below. How far above the ground is the bird’s new location

Write the expression as a constant , a single trigonometric function, or a power of a trigonometric function. sin x cos x/ tan x

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy

Which of the following is true for the relation f(x)=2x^2+1
