Derivative of xtx
WebTranscribed Image Text: (a) Find a function f that has y = 4 – 3x as a tangent line and whose derivative is equal to ƒ' (x) = x² + 4x + 1. (b) Find the area under the curve for f (x) = x³ on [−1, 1]. e2t - 2 (c) Determine where the function is f (x) = cos (t²-1) + 3 (d) Express ² sin (x²) dx as limits of Riemann sums, using the right ... WebHere we make use of the property of the derivative of product: (u(x)v(x))0= u0(x)v(x) + u(x)v0(x). The notation r A:u(A)means to calculate the derivative w.r.t. Aonly on u(A). Same ap- plies to r AT:v(A ). Here chain rule is used. Note that the conversion from r A:v(AT)to r AT:v(AT) is based on Eq.5. 4 An Example on Least-square Linear Regression
