Webf'(x) = (-1/x 2)cos(1/x) Find critical values. 0 = (-1/x 2)cos(1/x) 0 = cos(1/x) π/2 = 1/x. 2/π = x. Use test points. f'(0.5) = (-1/0.5 2)cos(1/0.5) = -4cos(2) = 1.664 > 0. f'(1) = (-1/1 2)cos(1/1) = -cos(1) = -0.54 < 0. As the function's derivative decreases between these two test values, it is clear that the sequence f(x)=sin(1/x) is ...

Web1. dy dxsin − 1(x)2 = dy dx(sin − 1(x))2 It can be seen that this is a composition of two functions f(g(x)), where f(x) = x2 and g(x) = sin − 1(x). Therefore we need to apply chain rule to this. The chain rule is: (f ∘ g) ′ (x) = f ′ (g(x)) ⋅ g(x) Let,s apply that to our derivative. dy dx(sin − 1(x)))2 = 2(sin − 1(x))1 ⋅ dy ... WebNov 23, 2024 · Combine ( 2) and ( 3) : (4) f ′ ( sin θ) cos θ = 1. Divide by cos θ on both sides of ( 4) : (5) f ′ ( sin θ) = 1 cos θ. Let x = sin θ. Then 1 − x 2 = cos 2 θ, and since − π 2 ≤ θ ≤ π 2, it follows that cos θ ≥ 0, so we have cos θ = 1 − x 2. Making these substitutions in ( 5) , f ′ ( x) = 1 1 − x 2. But f ′ ( x ...
