-0.3 is the. correct answer.
Can you tell us what the expression is in the question?
Answer:
21.25
Step-by-step explanation:
85/4 = 80/4+5/4 = 20 + 1 + 1/4 = 21 + 0.25 = 21.25
Answer:
1) ∫ x² e^(x) dx
4) ∫ x cos(x) dx
Step-by-step explanation:
To solve this problem, eliminate the choices that can be solved by substitution.
In the second problem, we can say u = x², and du = 2x dx.
∫ x cos(x²) dx = ∫ ½ cos(u) du
In the third problem, we can say u = x², and du = 2x dx.
∫ x e^(x²) dx = ∫ ½ e^(u) du
