- This 213-acre conservation area is an extensive forested wetland system and contains old-growth temperate rainforest and coastal sphagnum bog habitats. The forest- dominated by western redcedar, Sitka spruce, and western hemlock-includes many trees more than 500-years old. An unusual, low-elevation Pacific silver fir plant community also occurs within the conservation area.
- 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.
