Solving Complex Equation Examples Example 3: Solve for h. {eq}5i = (6hi + 2)(5i - 8) {/eq} 1) This is a complex math equation that involves complex numbers and an imaginary number. The complex numbers are {eq}(6hi + 2) {/eq} and {eq}(5i - 8) {/eq}. The purely imagina...
The equation of a hyperbola with a horizontal axis is (x2/ a2) - (y2 / b2) = 1 where a and b are positive constants. A circle has a constant distance from the center point, while a hyperbola is a curve that has two focus points (+ae, 0), and (-ae, 0). What is the diff...

(1) The absolute value of |A| equals 1 (that is, ||A|| = 1), (2) A*=A−1=A¯T is unitary, and (3) AB is unitary. The proof of part (1) is left as Exercise 4, while the proofs of parts (2) and (3) are left as Exercise 5. The next two theorems are the anal...
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...
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) ...
When the roots are complex numbers—λ1=p+qi and λ2=p−qi, where p and q are real numbers—the two corresponding solutions of the differential equation ay″+by′+cy=0 are y1(t)=e(p+qi)t and y2(t)=e(p−qi)t. At this point, a crucial fact to know is Euler's formula,...
(1) where\({\mathcal{H}}\)is the hypnosis space and\(I( \cdot )\)is an indicator function, which equals 1 when the expression holds and 0 otherwise. A validation set\({\mathcal{D}}_{val}\)is drawn from the same distribution as the training set\({\mathcal{D}}_{tr}\)and ...
Noticeably, the linear fractional complex network (4) denoted by a pair of matrices (𝐴+𝐶,𝐵)(A+C,B) is controllable if the rank of 𝑄𝐹QF equals N. In particular, Theorem 1 is also true for network (5) with matrix 𝐶=0C=0, i.e., when it (5) degenerates into 𝐶...
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(...
