Answer 2

HELLO DEAR,


differentiation of secx

We know that:-

secx = 1/cosx

using (quotient rule) = [ (deno.*derivative of num.) - (num.*derivative of deno.) ] /(denominator)²


⇒[ cosx*d(1)/dx - 1*d(cosx)/dx] / (cosx)²

⇒[ cosx(0) - (-sinx) ] / (cosx)²

⇒sinx/cos²x

⇒sinx/cosx * 1/cosx

⇒tanxsecx



I HOPE ITS HELP YOU DEAR,
THANKS
