I got a 7 for my Mathematics HL internal assessment in 2020. The topic was “Investigating the relationship between the golden ratio and the Fibonacci sequence in calculus”

1. Introduction
During my IB psychology course, I was introduced to the golden ratio and its application in the beauty standards. It was quite peculiar to generalize such a ratio to the standards that change over time and do not have a high cross-cultural validity as different cultures perceive beauty differently. Having such a number and emphasizing its connection to the real world seemed quite interesting, and thus I decided to research a bit further on my own. When investigating, I landed on Fibonacci sequence and its relation to the golden ratio – it was indeed interesting yet no prominent source went into depth in analysing their relationship. I was really interested in how a sequence developed respectively from a ratio could have such strong ties – especially in topics that we have covered during the IB mathematics HL courses such as calculus. Consequently, I decided to complete my math internal assessment on this topic; the aim of this investigation is to come to a stronger understanding of the connection between the Fibonacci sequence and the golden ratio – to find its relevance in calculus…
