Evaluate the integral by making the given substitution. (Use C for the constant of integration.) sin3(θ) cos(θ) dθ , u = sin(θ)

chubhunter [2.5K]

Evaluate int[sin^3(θ)cos(θ)dθ] with u = sin(θ)
du/dθ = cos(θ), dθ = du/cos(θ)

The integral becomes:
int[u^3•cos(θ)du/cos(θ)]
= int[u^3•du]
= u^4/4 + C

Substitute u = sin(θ) to get back a function of θ:
sin^4(θ)/4 + C

Round to the nearest tenth

Volume of cylinder = pi*r^2*h
Volume of sphere = 4/3*pi*r^3

Let the radius and height be 2

Cylinder = pi * 2^2 * 2 = 8pi = 25.1
Volume = 4/3 * pi * 2^3 = 32/3pi = 33.5

33.5 / 25.1 = 1.33
32/3 pi / 8 pi = 4/3

Four thirds of the cylinder’s volume is the sphere’s volume

What is the factored form of x2 – 6x – 16? (x – 4)(x – 2) (x + 4)(x – 2) (x – 2)(x + 8) (x – 8)(x + 2)

Mrac [35]

Answer:

(x-8) (x+2)

Step-by-step explanation:

x^2 – 6x – 16

Factor

What 2 numbers multiply to -16 and add to -6

-8 *2 = -18

-8+2 = -6

(x-8) (x+2)
