The document summarizes trigonometric addition formulas and related formulas. It provides proofs of the formulas using properties of coordinates on the unit circle. Specifically, it proves formulas for cosine, sine, and tangent of the sum or difference of two angles α and β using the x-y coordinates of points on two superimposed unit circles with angles of α, β, α+β, and -β.
- The document discusses optical motion capture, which uses cameras to capture markers placed on joints to analyze motion by reconstructing a skeletal model and estimating joint angles and forces over time.
- It questions how the 2D camera images are reconstructed into 3D space, how actual lengths are determined when cameras only see sensor lengths, and how joint torques and muscles forces are estimated using only cameras and force plates.
- Matrices play a large role in the calculations needed to address these questions in optical motion capture.

Unit-1 covers topics related to error analysis, graphing, and logarithms. It discusses types of errors, propagation of errors through addition, subtraction, multiplication, division, and powers. It also defines standard deviation and provides examples of calculating it. Graphing concepts like dependent and independent variables, linear and nonlinear functions, and plotting graphs from equations are explained. Logarithm rules and properties are also introduced.
This document discusses algebraic functions, including polynomial and rational functions. Polynomial functions are functions of the form y = p(x) = a0 + a1x + a2x2 + ... + anxn, where ai ∈ R and an ≠ 0. Rational functions are functions of the form y = R(x) = P(x)/Q(x), where P(x) and Q(x) are polynomial functions. The document outlines how to analyze the domain, intercepts, symmetries, asymptotes, and graph of algebraic functions. It provides examples of discussing these "aids to graphing" and sketching the graphs of specific rational functions.

This document discusses key statistical concepts including random variables, probability distributions, expected value, variance, and correlation. It defines discrete and continuous random variables and explains how probability distributions assign probabilities to the possible values of a random variable. It also defines important metrics like expected value and variance, and how they are calculated for discrete and continuous random variables. The document concludes by explaining correlation, how the correlation coefficient measures the strength and direction of linear association between two variables, and how it is calculated.

This is an in-depth analysis of the way different types of sampling distribution works focusing on their specific functions and interrelations as part of the discussion on the theory of sampling.
This document discusses linear correlation and linear regression. It defines linear correlation as showing the linear relationship between two continuous variables, while linear regression is a multivariate technique used when the outcome is continuous that provides slopes. Linear regression assumes a linear relationship between an independent and dependent variable, normally distributed dependent variable values, equal variances, and independence of observations. Least squares estimation is used to calculate the intercept and slope that minimize the squared differences between observed and predicted dependent variable values. The slope's significance can be tested using a t-test.
This document discusses linear correlation and linear regression. It defines linear correlation as showing the linear relationship between two continuous variables, while linear regression analyzes the relationship between a continuous outcome (dependent) variable and one or more independent (predictor) variables. Linear regression finds the line of best fit to model this relationship and estimates coefficients that can be tested for statistical significance. The assumptions of linear regression include a linear relationship between variables, normally distributed errors, homogeneity of variance, and independent observations.

Key assumptions of linear regression include a linear relationship between variables, normally distributed errors, homogeneity of variance, and independence of observations. The significance of regression coefficients can be tested using t-tests and the standard error of the coefficients is also discussed.

It defines linear correlation as showing the linear relationship between two continuous variables, while linear regression is a multivariate technique used when the outcome is continuous that provides slopes. Linear regression assumes a linear relationship between the predictor and outcome variables, normality of the outcome at each value of the predictor, equal variances of the outcome, and independence of observations. It also discusses calculating the slope and intercept via least squares estimation to find the line that best fits the data by minimizing residuals.
This document discusses correlation, regression, and the general linear model. It defines correlation as assessing the relationship between two variables, while regression describes how well one variable can predict another. Pearson's r standardizes the covariance between variables. Linear regression finds the best-fitting line that minimizes the residuals through the least squares method. The coefficient of determination, r-squared, indicates how much variance in the dependent variable is explained by the independent variable. Multiple regression extends this to include multiple independent variables. The general linear model encompasses linear regression and can analyze effects across multiple dependent variables.

This document provides an overview of statistical concepts for analyzing experimental data, including z-tests, t-tests, and ANOVAs. It discusses developing experimental hypotheses and distinguishing between null and alternative hypotheses. Key concepts explained include p-values, type I and type II errors, and determining statistical significance. Examples are given of applying a t-test and ANOVA to compare brain volume changes before and after childbirth. Limitations of statistical analyses with respect to including entire populations are also noted.
