In this article, we shall study Jacobi’s Method to find the solution of simultaneous equations. Example 01: Solve the following equations by Jacobi’s Method, performing three iterations only. 20x + y – 2z = 17, 3x + 20 y – z + 18 = 0, 2x – 3y + 20 z = 25. Solution: Given […]
In this article, we shall study to find the distance between two points using the distance formula when the coordinates of the two points are given. Example 01: Find the distance between the following pairs of points : (2, 3), (4, 1) Let A(2, 3) ≡ (x1, y1) and B(4, 1) ≡ (x2, y2) be […]
In this article, we shall study to find the value of trigonometric expressions involving standard angles. Trigonometric functions values of some standard angles are given below: Evaluate the following: Example 01: sin20c + sin2(π/6)c + sin2(π/3)c + sin2(π/2)c = (0)2 + (1/2)2 + (√3/2)2 + (1)2 = 0 + 1/4 + 3/4 + 1 […]

In this article, we shall study the use of the bisection method to solve an equation. Intermediate Value Theorem : If a function f is continuous on closed interval [a, b] and f (a). f (b) < 0, i.e. ƒ (a) and ƒ (b) are opposite signs, then there exists at least one c ∈ […]
A circle is defined as the locus of all the points in a plane, which are at a fixed distance from a fixed point. The fixed point is called the centre of the circle and the fixed distance is called the radius of the circle. The radius of a circle is denoted by the letter […]
