Approximate the definite integral using the trapezoidal rule for the given value of n. Give the result accurate to 3 decimal places. (a) π 0 sin(x) dx n = 6 1.954 Correct: Your answer is correct. (b) Find the upper bound for the absolute value of the error based on |f ''(x)| and Theorem 1. |ET| ≤ .044 Incorrect: Your answer is incorrect. (c) Find the exact value of the definite integral. Correct: Your answer is correct.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
