WebSep 7, 2024 · We can find the derivatives of sinx and cosx by using the definition of derivative and the limit formulas found earlier. The results are. d dx (sinx) = cosx and d … WebThe chain rule of partial derivatives is a technique for calculating the partial derivative of a composite function. It states that if f (x,y) and g (x,y) are both differentiable functions, and y is a function of x (i.e. y = h (x)), then: ∂f/∂x = ∂f/∂y …

WebI have done the following: Write sinx = eix − e − ix 2i, then we have f(x) = 1 2i ⋅ (e ( 1 + i) x − e ( 1 − i) x). Taking the derivatives: f ( n) (x) = 1 2i ⋅ ((1 + i)ne ( 1 + i) x − (1 − i)ne ( 1 − i) x) Now, I use that: (1 + i)n = √2n ⋅ (cosnπ 4 + isinnπ 4)(1 − i)n = √2n ⋅ (cos− nπ 4 + isin− nπ 4) Web10 years ago. That's because of the chain rule. In simple terms, when deriving e^A, you will get A'e^A, A' being the derivative of A. Since in the case of e^x, the derivative of x is 1, you simply get e^x. If it was e^2x however, then you would get 2e^2x, due to the derivative of 2x being 2. 1 comment. ( 84 votes) philip talboy cdc
