The instruments used in data collection include video recording transcription, and survey. Twenty-four students from a secondary school in Kuala Nerus, Terengganu participated in this study. This study was designed based on a mixed-method research by using quantitative and qualitative data. The objectives are to identify the impact of using Wordwall on students’ participation in the ESL classroom and to examine the students’ perception of using Wordwall in the ESL classroom. \begin(x, y) = $.This research was conducted to investigate the use of Wordwall to improve students’ engagement in an ESL classroom. When $M$ and $N$ are two functions defined by $(x, y)$ within the enclosed region, $D$, and the two functions have continuous partial derivatives, Green’s theorem states that: Suppose that $C$ is a simple, piecewise smooth, and positively oriented curve lying in a plane, $D$, enclosed by the curve, $C$. It is important that we know these terms and some properties of curves before establishing Green’s theorem. The curve shown is also simple because it goes through the path with no loops while the region is considered simply connected because it encloses no holes. This also means that when the path of the curve is in a clockwise direction is negatively oriented. Throughout our discussion, for consistency, we consider the curve positively oriented when it follows a counterclockwise direction. The curve, $C$, is going around in a counterclockwise direction. The graph above highlights a closed curve defined by $C$ and the enclosed region is labeled as the region, $D$. It allows us to find the relationship between the line integral and double integral – this is why Green’s theorem is one of the four core concepts of the fundamental theorem of Calculus.īefore we discuss the formula for Green’s theorem, let’s go first to take a look at the curve shown above. Green’s theorem allows us to integrate regions that are formed by a combination of a line and a plane. Being familiar with the process of evaluating line integrals and knowing how to apply the fundamental theorem for the line integral.įor now, let’s break down the important components of Green’s theorem and understand the theorem’s definition.Understanding the second part of the fundamental theorem of calculus.Knowing how to evaluate iterated integrals.Before we proceed, make sure that you have a strong grasp on the following topics: We’ll also cover the general form of Green’s theorem and its many applications. Our discussion will cover the fundamentals of Green’s theorem – from its definition to its proof. Through Green’s theorem, we can rewrite line integrals in terms of double integrals. Green’s Theorem allows us to connect our understanding of line integrals and integration of multivariable functions. When a line integral is challenging to evaluate, Green’s theorem allows us to rewrite to a form that is easier to evaluate. This theorem helps us understand how line and surface integrals relate to each other. Green’s Theorem is one of the most important theorems that you’ll learn in vector calculus.
