Hi, can i ask what is the differentiate of (1+x^3/2x^2)? Please Thanks thanks for answering my first question :)

Redirected from "Suppose that I don't have a formula for g(x) but I know that g(1) = 3 and g'(x) = sqrt(x^2+15) for all x. How do I use a linear approximation to estimate g(0.9) and g(1.1)?"

use formula

Explanation:

differentiation of (u(x))/(v(x)) = (u'(x).v(x) - v'(x).u(x))/(v(x))^2
by applying formula we get
(6x^4 - 4x - 4x^4)/(4x^4)
=> (2x^4 - 4x)/(4x^4)
hope u find it helpful :)
