- 1Integration By Substitution
- 2Example: Integrate sec^3 x tan x dx Use the substitution u=sec xStep 1: Differentiate u
du/dx= sec x tan x - 3Step 2: Separate the variables du= sec x tan x dxStep 3: Substitute!
I= sec^2 x sec x tan x dx
I= sec^2x du
I=u^2 du - 4Step 4: Integrate I=1/3 u^3Step 5: Substitute x back in
I=1/3 sec^3 x
