Homework Statement
The Attempt at a Solution
My book is not explaining very well the steps at solving these problems. There is a step that I'm missing
step 1. find 1/(b-a) easy
step 2. find the antiderivative of 4 - x, easy, x^2/2
step 3. plug in what the result of the antiderivative is for b and a, subtract b from a
step 4. this is the step I'm missing. the books shows that I'm supposed to multiply 4 by b - a. why? what is this? I need to know what mathematical terminology this is so that i can do these problems in the future
step 5. subtract step 4 from step 3. why? what mathematical terminology is this.
step 6. multiply step 1 by step 5, I understand that.
I'm not yet able to read the notation and the book is not helping.
