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
Answer:
This is trapezium.
Area of this figure =1/2h(d1-d2)
1/2×5(14-8)
=30/2
=15cm^2
The answer would be “Greater than.”
<span>It
has no perfect square factors, unless you count 1 = 1^2. That's sort
of a degenerate case we don't usually count, since every integer has
that factor. We would usually say that 1290 is a square-free integer. Hope this helps!!</span>
