Regula–Falsi Method is a numerical method / explain example

Regula–Falsi Method is a numerical method for estimating the roots of a polynomial f(x).

EXAMPLE:   Consider f(x) = x3 + 3x – 5, where [ a = 1, b = 2 ] and DOA = 0.001.

what is Integration in maths

  Integration in Mathematics Integration is a fundamental concept in calculus that represents the accumulation of quantities. It is the reverse process of differentiation and is used to find areas, volumes, central points, and many other useful things. 1. Why is Integration Important? Finds Area under curves. Calculates Volume in 3D spaces. Solves Differential Equations in physics and engineering. Used in Probability & Statistics for continuous distributions. 2. Types of Integration 1️⃣ Indefinite Integral (Without Limits) Represents the antiderivative of a function. Formula: ∫ f ( x ) d x = F ( x ) + C \int f(x) dx = F(x) + C where C C is the constant of integration. Example: ∫ x 2 d x = x 3 3 + C \int x^2 dx = \frac{x^3}{3} + C 2️⃣ Definite Integral (With Limits) Computes a numerical value over an interval [ a , b ] [a, b] . Formula: ∫ a b f ( x ) d x = F ( b ) − F ( a ) \int_{a}^{b} f(x) dx = F(b) - F(a) Example: ∫ 0 3 x 2 d x = [ x 3 3 ...

What is unit vector :- explain unit vector

Electromagnetic fields Unit vector- A unit vector has a function to indicate the direction. Its magnitude is always unity, irrespective of the direction which it indicates and the co-ordinate system under consideration. Thus for any vector, to indicate its direction a unit vector can be used. Consider a unit vector āoA in the direction of OA as shown in o the Fig. This vector indicates the direction of OA but its magnitude is unity. Fig Unit vector aOA So vector OA can be represented completely as its magnitude R and the direction indicated by unit vector along its direction. ŌĀ = |OA| āOA =R āOA āOA=1
