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

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

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

Using quotient rule differentiate tan x w.r.t.x

d/dx(tan x) =………

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

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

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

Solve the following differential equations (dy)/(dx) + sec x y = tan x ( 0 le x lt pi/2)

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)

Using product rule differentiate (1-2tan x) ( 5 + 4 sin x) w.r.t.x
