Найдите производную функции: 1. f(x) = 2x^3-x^2-7x 2. f(x) = 2tgx

f(х) = (8^х + e^х) = (8^х) + (e^х) = 8^х * ln 8 + e^х.

f(х) = (e^х х^2) = (e^х) (х^2) = e^х 2 * х^(2 1) = e^х 2 х^1 = e^х 2 * х = e^х 2х.

y = ((2х^2 + 1) * e^х) = (2х^2 + 1) * e^х + (2х^2 + 1) * (e^х) = ((2х^2) + (1)) * e^х + (2х^2 + 1) * (e^х) = (2 * 2 * х^(2 1) + 0) * e^х + (2х^2 + 1) * e^х = 4х * e^х + (2х^2 + 1) * e^х = (2х^2 + 4х + 1) * e^х.

f(х) = (х 1) = (х) (1) = (1 * х^0) 0 = 1 * 1 0 = 1 0 = 1.

f(х) = (1 2х 3х^2) = (1) (2х) (3х^2) = 0 2 3х = -2 3х.
