WebAug 18, 2024 · We can find the derivatives of sin x and cos x by using the definition of derivative and the limit formulas found earlier. ... Notice that at the points where \(f(x)=\sin x\) has a horizontal tangent, its derivative \(f′(x)=\cos x\) takes on the value zero. We also see that where f\((x)=\sin x\) is increasing, \(f′(x)=\cos x>0\) and where ... WebSep 7, 2024 · The inverse of g(x) = x + 2 x is f(x) = 2 x − 1. We will use Equation 3.7.2 and begin by finding f′ (x). Thus, f′ (g(x)) = − 2 (g(x) − 1)2 = − 2 (x + 2 x − 1)2 = − x2 2. g′ (x) = 1 f′ (g(x)) = − 2 x2. We can verify that this is the correct derivative by applying the quotient rule to g(x) to obtain. g′ (x) = − 2 x2.
