WebbGaussian integrals. The simplest Gaussian integral involves one variable φ, I1 = Z ∞ −∞ dφe−K 2 φ 2+hφ = r 2π K eh 2 2K. (II.54) By taking derivatives of the above expression with respect to h, integrals involving powers of φ are generated; e.g. d dh: Z ∞ −∞ dφ φe−K 2 φ 2+hφ = r 2π K eh 2 2K · h K, d2 dh2: Z ∞ − ... WebbSimplify the following expression: (−5x−2y) (−2x−3y2) Again, I can work either of two ways: multiply first and then handle the negative exponents, or else handle the exponents and then multiply the resulting fractions. I'll show both ways. multiplying first: \left (-5 x^ {-2} y\right)\left (-2 x^ {-3} y^2\right) (−5x−2y)(−2x−3y2)

Any expression that has negative exponents is not considered an expression in its simplest form. We simply flip the fraction and convert the negative exponent to a positive exponent. north middlesex ayf
