DOUBLE INTEGRALS : INTRODUCTION #double #integrals #introduction
DOUBLE INTEGRALS The line integrals are often used to find the lengths of the curves i.e if we talk about a circle the line integral is the circumference of the circle or semi circle or quarter circle etc. If we ask about the length of the curve on the circle which is not a complete circle or semi or quarte circle , we chose the part of the circumference of the circle then we need some procedure or theory to find the length of the curve which are called the line integrals. This process of line integration is applicable not only for the circles but also for any one or two or three dimensional regular and irregular shapes . So what about the surface area of circular cake in a rounded plate or cool drink bottle looks like a cylinder or football like a sphere etc. In mathematics there are certain formulae for the ab...
