Find `d/(dx) (x/(1 + tan x))`

Find d/(dx) ( 1 + tan x)

Using quotient rule find d/(dx) ((x tan x )/(sec x + tan x))

What are the values of d/(dx) (cos x) and d/(dx) ( tan x)

d/dx(tan x) =………

Using the product rule and the relation tan x cos x = sin x , find d/(dx) (sin x)

Writing cos x = (sin x)/(tan x) and apply quotient rule find d/(dx) (cos x)

Fill in the blanks d/(dx) (5x^2 - 7x +1) =..............

If d/(dx) {f(x)}=1/(1+x^2) then d/(dx){f(x^3)} is a) (3x)/(1+x^3) b) (3x^2)/(1+x^6) c) (-6x^5)/(1+x^6)^2 d) (-6x^5)/(1+x^6)

Given that d/(dx) (c_1u_1 +- c_2u_2 +- .........+- c_nu_n) = c_1d/(dx)(u_1) +- c_2d/(dx)(u_2) +- ....... +- c_nd/(dx)(u_n) and d/(dx) (c) = 0 if c,c_1,c_2,...........,c_n are constants and u_1, u_2,.....,u_n are functions of x. Using the given results, evaluate d/(dx) ((3x^2 + 12x - 11)/x)
