WebThe derivative of the cosine function is written as (cos x)' = -sin x, that is, the derivative of cos x is -sin x. In other words, the rate of change of cos x at a particular angle is given … WebThe derivative of cos(θ) cos ( θ) with respect to θ θ is −sin(θ) - sin ( θ). θcos2(θ)+sin(θ)(θ(−sin(θ))+cos(θ) d dθ[θ]) θ cos 2 ( θ) + sin ( θ) ( θ ( - sin ( θ)) + cos ( θ) d d θ [ θ]) Differentiate using the Power Rule. Tap for more steps... θcos2(θ)+sin(θ)(θ(−sin(θ))+cos(θ)) θ cos 2 ( θ) + sin ( θ) ( θ ( - sin ( θ)) + cos ( θ)) Simplify.
WebAs MJD suggests in the comments, we need to use the chain rule which basically states that: outside → f ( g ( x) ⏟ inside) = [ derivative of the outside evaluated at the inside] × [ derivative of the inside] We know that: d d x cos ( x) = − sin ( x) and d d x x 3 = 3 x 2. So by the chain rule: d d x cos 3 ( x) = d d x [ cos ( x ... WebJun 25, 2024 · Calculus Differentiating Trigonometric Functions Derivative Rules for y=cos (x) and y=tan (x) 1 Answer Jim G. Jun 25, 2024 −sin2x Explanation: differentiate using the chain rule given y = f (g(x)) then dy dx = f '(g(x)) × g'(x) ← chain rule y = 1 +(cosx)2 dy dx = 2cosx × d dx (cosx) dy dx = −2sinxcosx = −sin2x Answer link
WebNov 16, 2024 · This appears to be done, but there is actually a fair amount of simplification that can yet be done. To do this we need to factor out a “-2” from the last two terms in the numerator and the make use of the fact that \({\cos ^2}\left( \theta \right) + {\sin ^2}\left( \theta \right) = 1\).
