The Indonesian one hundred thousand rupiah banknote (Rp100,000) is a denomination of the Indonesian rupiah. Being the highest and second-newest denomination of the rupiah (after the Rp2,000 note), it was first introduced on November 1, 1999, as a polymer banknote [1] [2] before switching to cotton paper in 2004; [3] all notes have been printed using the latter ever since.
The 100 rupiah coin was first introduced in 1973 as a cupronickel coin weighing 9.72 g (0.343 oz). It had a diameter of 28.5 millimetres (1.12 in) and was 1.77 mm (0.070 in) thick. Its obverse featured the denomination ("100") in its center with the lettering "BANK INDONESIA," two stars, and the mint year (1973).
At the point of devaluation (November 1978), the trade-weighted real (local price adjusted) effective exchange rate of the rupiah [37] against major world currencies was just over twice as high as it was in 1995 (prior to the Asian economic crisis, and free fall of the rupiah), i.e. the rupiah was highly overvalued at this point. By March 1983 ...
For example, the cosine and sine of 2π ⋅ 5/37 are the real and imaginary parts, respectively, of the 5th power of the 37th root of unity cos(2π/37) + sin(2π/37)i, which is a root of the degree-37 polynomial x 37 − 1.
Ptolemy's theorem states that the sum of the products of the lengths of opposite sides is equal to the product of the lengths of the diagonals. When those side-lengths are expressed in terms of the sin and cos values shown in the figure above, this yields the angle sum trigonometric identity for sine: sin(α + β) = sin α cos β + cos α sin β.
In mathematics, the values of the trigonometric functions can be expressed approximately, as in (/), or exactly, as in (/) = /.While trigonometric tables contain many approximate values, the exact values for certain angles can be expressed by a combination of arithmetic operations and square roots.
In radians, one would require that 0° ≤ x ≤ π/2, that x/π be rational, and that sin(x) be rational. The conclusion is then that the only such values are sin(0) = 0, sin(π/6) = 1/2, and sin(π/2) = 1. The theorem appears as Corollary 3.12 in Niven's book on irrational numbers. [2] The theorem extends to the other trigonometric functions ...
37 is a prime number, [1] a sexy prime, and a Padovan prime 37 is the first irregular prime with irregularity index of 1. [2] 37 is the smallest non-supersingular prime in moonshine theory. 37 is also an emirp because it remains prime when its digits are reversed.
