Question

if f x is equals to (x^a/x^b)^a+b×(x^b/x^c)^b+c×(x^c/x^a)^c+a, find differentiation of fx.​

Answer 1

Answer:

Let f(x)

ax

2

+bx+c

1

Thus by quotient rule

f

′

(x)=

(ax

2

+bx+c)

2

(ax

2

+bx+c)

dx

d

(1)−

dx

d

(ax

2

+bx+c)

=

(ax

2

+bx+c)

2

(ax

2

+bx+c)(0)−(2ax+b)

=

(ax

2

+bx+c)

2

−(2ax+b)
