WebWe derive the derivatives of inverse trigonometric functions using implicit differentiation. Now we will derive the derivative of arcsine, arctangent, and arcsecant. The derivative of arcsine. d dxarcsin(x) = 1 1−x2√. Recall. arcsin(x) =θ. means that sin(θ) =x and −π 2 ≤ θ≤ π 2. Implicitly differentiating with respect x we see. WebAug 4, 2024 · Explanation: differentiate using the chain rule. given y = f (g(x)) then. dy dx = f '(g(x)) × g'(x) ← chain rule. y = (lnx)4. ⇒ dy dx = 4(lnx)3 × d dx (lnx) ⇒ dy dx = 4(lnx)3 x.
