What is 2/4 in simplest form
Gennadij [26K]
2/4 in simplest form:

First, to find the simplest form of a fraction, you'll need to find the greatest common factor (GCF). To do this, we can list the factors of 2 and 4 and find the first common one.

Factors of 2: 1, 2
Factors of 4: 1, 2, 4

Since 2 is our first common factor, it is our GCF.

Second, we can now take our GCF (2) and divide it with our numerator and denominator. We will get a new numerator and denominator.

2 \div 2 = 1  \\  4 \div 2 = 2

Answer in fraction form: \fbox {1/2}
Answer in decimal form: \fbox {0.5}

Set up a triple integral in spherical coordinates to compute the volume of the region inside the sphere x² + y² + z² = 4 and abo
Mademuasel [1]

The plane meets the sphere in the cylinder

z=1 \implies x^2+y^2+1^2 = 4 \implies x^2+y^2 = 3 = \left(\sqrt3\right)^2

In spherical coordinates, the plane has equation

z = \rho\cos(\phi) = 1 \implies \rho = \sec(\phi)

and since

\begin{cases}x = \rho\cos(\theta)\sin(\phi) \\ y=\rho\sin(\theta)\sin(\phi)\end{cases} \implies x^2+y^2 = \rho^2 \sin^2(\phi)

the cylinder has equation

\rho^2 \sin^2(\phi) = 3 \implies \rho = \sqrt3 \, \csc(\phi)

The plane and cylinder thus meet when

\sec(\phi) = \sqrt3\,\csc(\phi) \implies \tan(\phi) = \sqrt3 \implies \phi = \dfrac\pi3

So, the volume of the region is given by

\displaystyle \boxed{\int_0^{2\pi} \int_0^{\pi/3} \int_{\sec(\phi)}^2 \rho^2 \sin(\phi) \, d\rho \, d\phi \, d\theta}
