1.
If f (a) = 4x sin -1 (a), find f' (x) = f' (0.4) = Note: Don't try to use sin (a) in your answers; use arcsin (x) insteadFind the derivative of the function f(x) = 2x arccos(2x - 1 - 4x2 f' (x) =If f(a) = 8 sin(7x)sin -1(x), f' (x) =If f(x) = 5 arctan (6x), find f' (x). Find f'(2).Let f(x) = (4 sin x + 3 cos x) arctan x f' (x) =Given at) = sin103), find the equation of the line tangent to x) at a: = 7 Round your values to two decimal places. m A small plane, moving at 100 , flies horizontally on a line 500 meters directly above an observer. .9 Let 3 be the angle of elevation between the plane and the observer and let a: be the horizontal distance between the plane and the observer.
