You have a rational expression whose numerator's degree is smaller than the denominator's. This tells you you should consider a partial fraction decomposition. We want to rewrite the integrand in the form


You can use the "cover-up" method here to easily solve for
. It involves fixing a value of
to make 2 of the 3 terms on the right side disappear and leaving a simple algebraic equation to solve for the remaining one.
- If
, then 
- If
, then 
- If
, then 
So the integral we want to compute is the same as

and each integral here is trivial. We end up with

which can be condensed as

In analyzing the given diagram which is a combination of two right angle triangle, the value of sin∠L is 5/13.
<h3>What is the value of sin∠L?</h3>
Given that angle ONM is a right angled triangle, we can find length of OM using the Pythagorean theorem.
c = √( a² + b² )
OM = √( 4² + 3² )
OM = √( 16 + 9 )
OM = √25
OM = 5
Next, angle OML is also a right angled triangle, we can get the hypotenuse LO.
c = √( a² + b² )
LO = √( OM² + ML² )
LO = √( 5² + 12² )
LO = √( 25 + 144 )
LO = √169
LO = 13
Now, to get sin∠L, we use the mnemonic: SOHCAHTOA
sinθ = opposite / hypotenuse
sin∠L = OM / LO
sin∠L = 5/13
Therefore, in analyzing the given diagram which is a combination of two right angle triangle, the value of sin∠L is 5/13.
