Derivative of cos -3x
WebIf we accept that d/dx (cos x) = − sin x, and the power rule then: sec x ≡ 1/cos x Let u = cos x, thus du = − sin x dx sec x = 1/u (1/u) = (u⁻¹) By the power rule: derivative of (u⁻¹) = −u⁻² du Back substituting: = − (cos x)⁻² ( − sin x) ∙ dx = [sin x / (cos x)²] ∙ dx = [ (sin x / cos x) ∙ (1/cos x)] ∙ dx = [tan (x) ∙ sec (x)] ∙ dx 5 comments WebThe derivative of cosine is negative sine: Then, apply the chain rule.
