The given first-order nonlinear ordinary differential equation is separable, so
$$
\frac{dy}{dx} = 2(1+x)(1+y^2) \Rightarrow \frac{dy}{1+y^2} = 2(1+x)dx \Rightarrow \arctan{y} = x^2 + 2x + C \Leftrightarrow y(x) = \tan{(x^2 + 2x + C)}.
$$
Using the initial condition, we find $C$:

Multistage Rate Conversion
Multistage rate conversion is an approach that splits rate conversion into several stages. For example, instead of decimation by a factor of 18, decimate by factor of 3, followed by another

How many terms of the AP : 9, 17, 25, . . . must be taken to give a sum of 636?
Solution:
Let there be n terms of the AP. 9, 17, 25 …
For this A.P.,
First term, a = 9
Common difference, d = a [2]− a [1] = 17−9 = 8
As, the sum of n terms is;
S[n] = n /2 [2 a + (n – 1) d ]
636 = n /2 [2 × a + (8 – 1) × 8]

For ${x^2} + 2x + 5$ to be a factor of ${x^4} + p{x^2} + q$, the values of $p$ and $q$ must be, respectively.
Hint:
Divide the polynomial ${x^4} + p{x^2} + q$ with its factor ${x^2} + 2x + 5$ and find the remainder. If a polynomial is divided by its factor, then the remainder is equal to zero. Hence, equate the

The wind generates near-inertial internal waves by exciting currents in the surface mixed layer. Convergences and divergences in these motions then “pump” propagating near-inertial waves. Some energy

bius Mu Function Calculator
Möbius Mu Function Calculator
In elementary number theory, the Möbius Mu function, denoted μ(n), returns a value of -1, 0, or 1 depending on the factorization of n.
If n is greater than 1 and divisible by a square integer, μ(n) = 0. Otherwise, if n = 1 or n has an even number of distinct ... | 4 | [

Multiplying Multiples of Numbers Together
To multiply multiples of numbers togethers, it is sometimes easier to use the square of the base number and the factor within the other number.
Example:
13 × 26 =
Solution:
Notice that 26 is a multiple of 13 and, in fact, 26 = 2(13). Therefore, 13 × 26 = 13 × (13 × 2)... | 4 | [

Suppression of crystallization in saline drop evaporation on pinning-free surfaces
For sessile droplets of pure liquid on a surface, evaporation depends on surface wettability, the surrounding environment, contact angle hysteresis, and surface roughness. For non-pure liquids, the
