This article aims to find the double integral of the triangular region with vertices. This article uses the concept of double integration. The definite integral of a positive function of one variable represents the area of the region between graph of the function and the $x-axis$. Similarly, the double integral of a positive function of two […]

This article aims to find the area under the given curves. The article uses the background concept of the area under the curve and integration. The area under curve can be calculated in three simple steps. First, we need to know equation of the curve $(y = f(x))$, the limits over which area is to be calculated, and axis […]

How many international students would you expect to find in a typical cluster? With what standard deviation? This question aims to find the expected number of international students in a typical cluster along with their standard deviation. Take into consideration what a random variable is: a collection of numerical values resulting from a random process. […]

This problem aims to familiarize us with trigonometric laws. The concepts required to solve this problem are related to the law of cosines, or more commonly known as the cosine rule, and the significance of postulates. The Law of cosines represents the connection between the lengths of sides of a triangle with reference to the […]
