If f(x) has an inverse on [a, b], then integrating by parts (take u = f(x) and dv = dx), we can show
Let . Compute the inverse:
and we immediately notice that .
So, we can write the given integral as
Splitting up terms and replacing in the first integral, we get
Times means
2 times 3 means 3+3
4 times of 3=3+3+3+3
divide is
4 divided into 2 parts=2
6 divided into 3 parts=3
but you could multiply by a fraction and essensially divide
they are different
Answer:
The answer is - 5
Step-by-step explanation:
-2 - 4 + 3/2 - 3 + 5/2 ( the step after you replaced x with 3 and multiplied it )
-2 -4 -3 +
-9 + 4 = - 5
