This equation can be solved using the base 2 logarithm: 2x=16becomeslog2(2x) = log2(16)becomesx log2(2) = 4log2(2) = 1x*1=4equalsx = 4What is the difference between the natural logarithm and the base 2 logarithm? The natural logarithm uses e as the base and the log2 uses ...
By assuming (𝒜3)(A3) and using Equation (20), it is true that ∥(𝐺𝑥)(𝑡)∥≤𝑟1.∥(Gx)(t)∥≤r1. (21) Taking into account derivatives of (𝐺𝑥)(𝑡)(Gx)(t), one gets ∥(𝐺𝑥)′(𝑡)∥≤𝑟2𝑡𝑝−1𝑓Γ(2−𝑝).∥(Gx)′(t)∥≤r2...
A complex math equation is a math equation that involves complex numbers. Examples 1 and 2 detail how to add and multiply complex numbers, and the next section explores how to manipulate complex equations. Example 1: Add the complex numbers {eq}z = 3 + 5i {/eq} and {eq}n = 2 - 7...
Note that there is a minus sign in the real part since, at some point, we faced a multiplication of two imaginary numbers i ⋅ ii⋅i, which equals −1−1 by definition. Multiplying complex numbers isn't that scary. Is it? So what about dividing complex numbers? Let...
The equation equals Eq. (1.189), but the form is not divided into two conjugated eigenvalues, which are now enclosed in the expanded range 2N, so that (3.39)λr=λr+N⁎ and (3.40)Rr=Rr+N⁎. The impulse response based on the model (3.38) is (see also Eq. (1.91)) (3.41)h(...
It is clear that the equation cosh2θ−sinh2θ=1 holds, which reminds us of the equation of a hyperbola, x2−y2=1. This is why they are called hyperbolic functions. Note that cosθ is an even (symmetric) function of θ, so changing the sign of θ should not change...
Definition:The imaginary unit i is the solution to the equation x2+1=0. Imaginary unit has the property i2=-1 Let’s try to see what numbers we can get by raising the imaginary unit to other powers: i0=1 (Every number raised to zero power equals to 1) ...
In the context of complex numbers, a logarithm of the complex number z is any complex number w such that ew = z. This equation has no solution if z = 0, and it has infinitely many solutions otherwise: for any solution w, w + 2nπi is also a solution for all integers n. Solution...

Again, we see that we obtain equivalent results with DSolve. First, we find a general solution of the equation, naming the resulting output gensol. Clear[x,y] gensol=DSolve[x∧2y”[x]−5xy′[x]+10y[x]==0, y[x],x] {{y[x]→x3C[2]Cos[Log[x]]+x3C[1]Sin[Log[x]]}} No...
