| INFINITE SURDS | Ria Garg | | The purpose of my investigation is to find the general statement that represents all values of k in an infinite surd for which the expression is an integer. I was able to achieve this goal through the process of going through various infinite surds and trying to find a relationship between each sequence. In the beginning stages of my investigation I came across the sequence of ` a1= 1+1 a2= 1+1+1 a3 = 1+1+1+1 While looking at the sequence

Averages Method: Moving average of order N is the arithmetic average for the most recent N observations Exponential smoothing method: It combines both demand and forecast. The Current forecast is the weighted average of the last forecast and the current demand 1.1.2 Trend based methods: Regression Analysis: fits straight line to a set of data Holt’s Method : type of double exponential smoothing. Allows for simultaneous smoothing on the series and on the trend 1.2 Qualitative methods:

Logan’s Logo So Logan has devised a logo for her company which is a square divided into 3 sections with 2 functions. Our objective is to find what functions fit the two curves on her logo and also make it fit on two other sizes of her logo. Just looking at the shape of the lines 2 types of functions immediately jump into my head‚ sinusoidal and cubic. I first traced a grid onto the original copy of the logo I was given in order to get points to start trying to form a function to match the design
