- The Supreme Court ruled on the evening of April 10 [of 2023] that the Trump administration must comply with a lower court’s order to “facilitate” the release from custody of Kilmar Armando Abrego Garcia, an immigrant who was deported without a hearing to a mega prison in El Salvador. The case underscores the issue of due process and what legal protections are afforded to noncitizens.
- Euler’s formula (Wikipedia)
Euler’s formula, named after Leonhard Euler, is a mathematical formula in complex analysis that establishes the fundamental relationship between the trigonometric functions and the complex exponential function. Euler’s formula states that, for any real number x, one has eix = cos x + i sin x, where e is the base of the natural logarithm, i is the imaginary unit, and cos and sin are the trigonometric functions cosine and sine respectively. This complex exponential function is sometimes denoted cis x (“cosine plus i sine”). The formula is still valid if x is a complex number, and is also called Euler’s formula in this more general case.
