Question

What is the value
of d/dx (sin x tan x)?​

Answer 1

Answer:

sin x(sec x + 1)

Step-by-step explanation:

Use the chain rule:

d/dx(u*v) = u*dv/dx + v*du/dx

Let u = sin x ……. du/dx = cos x

Let v = tan x ……. dv/dx =  sec2 x

d/dx(sin x tan x) = sin x * sec^2x + tan x * cos x

= sin x * 1/ cos2x  + sin x/cos x * cos x = sin x/ cos2x + sin x = sin x(sec x + 1)
