Answer:
Evaluate ∫3x2sin(x3)cos(x3)dx
Step-by-step explanation:
hello (a) using the substitution u=sin(x3) because
du =3x²(cos x3)dx
you have ∫3x2sin(x3)cos(x3)dx = ∫udu=u²/2 +c............continu

Answer:
<h2>b. 3 - 2x</h2>
Step-by-step explanation:
The value of the 5 in 581.03 is 100 times the value of the 5 in 5.472
Step-by-step explanation:
Each digit in a number has a place value.
The place value of 4 in 453.56 is hundreds (100), because 4 is in the hundred place
The place value of 2 in 1782.56 is ones (1), because 2 is in the unit place
The place value of 3 in 2.345 is tenth (0.1), because 3 is in the tenth place
∵ The number is 581.03
- Find the place of 5 in the number
∵ 5 is in the hundred place
∴ The place value of 5 is 100
∵ The number is 5.472
- Find the place of 5 in the number
∵ 5 is in the unit place
∴ The place value of 5 is 1
To find the value of the 5 in 581.03 is how many times the value of the 5 in 5.472 divide the place values of them
∵ 100 ÷ 1 = 100
∴ The value of 5 in 581.03 = 100 times the value of 5 in 5.472
The value of the 5 in 581.03 is 100 times the value of the 5 in 5.472
