Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

∫cos 3x -cos 2x dx / cos x

∫cos 3x dx / cos x -∫cos 2x dx/cosx

∫4cos^3 x - 3cos x dx /cos x -∫2cos^2 x - 1 dx /cos x

∫4cos^2 x dx -3∫x dx -2∫cosx dx + ∫secx dx

∫4(1+cos 2x / 2) dx - 3x -2sinx+ln secx+tanx

2∫1+cos2x dx -3x -2sin x +ln secx+tanx

2{x+sin2x/2} -3x-2sinx+ln secx+tan x

2x+sin2x-3x-2sinx +ln secx+tan x

sin2x-2sinx-x+ln secx+tanx
