Sreative section - A a) b) Derive that the area of an equilateral triangle is v3 (side)”. Derive that the area of an isosceles triangle is 4 9 14p– q, where p is the length of each of two equal sides and q is the length of the base. If x, y, z are the three sides and s is the semi-perimeter of a triangle, derive that its area is Vs(s - x) (s - y) (s – z). c) - 83 Vedanta Excel in Mathematics - Book 10 32 Sca.. Date : Page: lala

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

i’m here for points.
