Pengontruksian Golden Ratio dari Barisan Fibonacci

2022-12-15T07:14:01+00:00

There are several ways to construct golden ratio, one of which is using the Fibonacci sequence. The Fibonacci sequence is a sequence that is formed from the addition of two terms, namely a term with the previous term. The construction process begins by forming a ratio sequence from the Fibonacci sequence. The process is continued by investigating the convergence of the sequence, starting from checking the limitations and monotony of the (rn) sequence. The investigation of the convergence of the sequence is continued by using the Cauchy criteria. The sequence is shown to be a Cauchy sequence, so is shown to be a convergent sequence. Because converges, further investigation is carried out to ﬁnd out the convergence point of the rn sequence which turns out to be convergent towards golden ratio.

Bagaimana Matematika Tumbuh Berdasarkan Pandangan Filsafat

2022-12-22T06:16:53+00:00

Abstract. Some mathematicians say that the questions that arise from what we know predicts what progress we will make and what we will know in the future. In predicting the growth of mathematics, it is necessary to know what experiments have been carried out by mathematicians with the goals that can be achieved so that they can determine a prediction. This study aims to determine the development of mathematics based on a philosophical view. This research method is a literature study. The results of the study show that based on a philosophical view, the growth of mathematics begins when a problem arises regarding the limited existence of mathematical objects, so that there is a need for an expansion of the number system. The growth of mathematics is also based on the existence of mathematicians who find many of the same things and many of the same sequences. Therefore, mathematicians claim that they do not make a mathematics but they are as instruments for the discovery of mathematics itself.

2022-12-22T08:30:55+00:00

The discussion of Analytic Philosophy that is often raised is very close to the philosophy of language. There are those who equate the study of analytic philosophy with a language philosophy. Analytical philosophy does pay attention to the use of language and the meaning conveyed. Of course, the characteristic of analytic philosophy which prioritizes links with language analysis should reveal the diversity of analytic philosophies. In this article, we will examine 4 philosophers who are in analytic philosophy, namely Edmund Husserl, Rudolf Carnap, Rudolf Quine, and Hillary Putnam. This research resulted in studies namely (1) philosophical studies showing the existence of logical analysis in a scientific concept and statement; (2) The thought used, the language used by humans must be tested as language as long as the thought is conveyed with or through language that allows it to achieve universal or logical power in the order of science or the language of science; (3) regarding all metaphysics based on non-empirical existence or perhaps belief in internal relations that are external. The observable world of plurality with external relations or is a logical entity.
