This study aimed at investigating the challenges of teaching mathematics to visual impaired students in school of the blind, a case study of some selected schools for the visually impaired. Questionnaire and interview were used for data collection from the respondents. The hypotheses in the study were tested using t-test with α-level of 0.05 through SPSS. The study followed a cross-section survey design and involved 80 respondents 20 for the visually impaired students, 10 for the Mathematics teachers, 10 special mathematics teachers, 40 low vision and non-visually impaired students. The findings revealed the visually impaired students receive bursaries from the government and non-government organization; meal, accommodation, and few scholastic materials from their school; extra time during mathematics classes and examination and friend support. However, constraining limitations in the method of instruction assessment used and the instructional materials provided were noted, on the basis of these findings, recommendation towards the better education of the visually impaired student studying mathematics should be encouraged and employment of special mathematics teachers.
We consider the integration of functions of two variables in a measure space. Some definitions, theorems and proves relating to measurable functions and measure space were considered by using Fubini's theorem. Application on the improvement of the Jensen's inequality with respect to the probability measure space is treated.
We discussed in this research a power series method for solution of a two-step reactive-diffusive equation with variable pre-exponential factor. A transformation was used to fit in the geometry of the model to allow an asymptotic series expansion which is invoked in a two compartmental regions with respect to the spatial variable. Adequate matching conditions were used at the interface between the two regions. The results were displayed graphically and compared with the previous work in the literature
There are distinct equations in the literature referred to as the Lamé equations. The equations are the Lamé equation in the algebraic form, Lamé equation in the Jacobi form, Lamé equation in the Weierstrass form, among others. It is well known that Lamé equation may be linked to one another through suitable variable transformations. The link between their solutions has not yet been investigated. The purpose of the present note is to establish a link between the solution of Lamé equation in its Weierstrass form which extends to an elliptic function and the solution of Lamé equation in the Jacobi form.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
