Trigonometric Substitutions
The three basic trigonometric substitutions are in the table below.
Integral Contains Try using Substitution
Va –
Va? + x?
? – a²
x = a sin 0, - <0<
I = a tan 0,
z = asec 8, 0<θ< 폴 or 플 <8<ㅠ
Part 1.
Using the substitution: z =
tan 0, -<0<, re-write the indefinite integral then evaluate in terms of 0.
dx =
Note: type 'theta' for 0 and 'dtheta' for de.
Part 2.
Back substituting in the antiderivative you found in Part 1. above we have
dz
Note: answer should be in terms of z only.
