3 dni temu · This method uses the algebraic identity. \ [ ( x - y ) ( x + y ) = x^2-y^2.\] For example, given the expression \ (\sqrt {a} - \sqrt {b},\) the conjugate is \ (\sqrt {a} + \sqrt {b},\) and multiplying by \ ( \frac { \sqrt {a} + \sqrt {b} } { \sqrt {a} + \sqrt {b} } \) gives.
6 dni temu · In calculus, there are 7 primary indeterminate numbers: \[\begin{array} &\frac{0}{0}, &\frac{\infty}{\infty}, &\infty-\infty, &\infty \cdot 0, &0^0, &\infty^0, &1^\infty.\end{array}\] Then, how do we find the values of limits in indeterminate form?
3 dni temu · Physics is celebrated for its ability to make extremely accurate predictions about tough problems such as the magnetic moment of electrons, the deflection of light by the Sun's gravity, or the orbit of the planets around the Sun. However, accuracy often comes at the cost of great difficulty in calculation.

1 dzień temu · The Riemann–Stieltjes integral of a real-valued function of a real variable on the interval [,] with respect to another real-to-real function is denoted by = (). Its definition uses a sequence of partitions of the interval [,] = {= < < < =}. The integral, then, is defined to be the limit, as the mesh (the length of the longest subinterval) of the partitions approaches , of the approximating sum
