Differentiate xcosx x c o s x with respect ..

Question 1 Report

Differentiate $\frac{x}{c o s x}$ with respect to x

1 + x sec x tan x

1 + sec2 x

cos x + x tan x

x sec x tan x + secx

Answer Details

let y = $\frac{x}{c o s x}$ = x sec x
y = u(x) v (x0
$\frac{d y}{d x}$ = U $\frac{d y}{d x}$ + V $\frac{d u}{d x}$
dy x [secx tanx] + secx
x = x secx tanx + secx
