In words: The sum of squares of two real numbers equals the product of a complex number with one of the two real numbers as its real part and the other as its imaginary part, and the conjugate of the complex number thus formed. difference of squares 平方差 a^2-b^2=(a+b)(a-b) ...
Step 1: Rationalize the DenominatorTo simplify the expression, we need to rationalize the denominator. We can do this by multiplying both the numerator and the denominator by the conjugate of the denominator, which is √5+2. √5+2√5−2×√5+2√5+2 Step 2: Apply the Difference of Sq...

Answer to: Write the complex conjugate of the complex number. Then multiply the number by its complex conjugate. -6 - sqrt(5)i. By signing up,...
\(\overline{\psi }\) is the conjugate of function ψ. The commonly used wavelet transform methods include continuous wavelet transform (CWT), discrete wavelet transform (DWT), etc., which essentially selects different translation and scale parameters continuously or discretely to obtain higher time...
Based on the theory of equal base circle bevel gears, a new type of gear, the equal base circle herringbone curved bevel gear, is studied further to reduce the axial force problem of curved bevel gears. Using the principle of equal basis circle herringbo

Suppose that and is the conjugate exponent to p, that is, . Then interpolation implies the Hausdorff–Young inequality, namely, (1.1) for all , where . We denote the best constant for this inequality, that is, the smallest possible value of C, by . This was found many years after the...
