Three points of a triangle are given; another point P is also given to check whether the point P is inside the triangle or not.To solve the problem, let consider the points of the triangle are A, B, and C. When the area of triangle Δ𝐴𝐵𝐶 = Δ𝐴𝐵𝑃 + Δ𝑃𝐵𝐶 + Δ𝐴𝑃𝐶, then the point P is inside the triangle.Input and OutputInput: Points of the triangle {(0, 0), (20, 0), (10, 30)} and point p (10, 15) to check. Output: Point is inside the triangle.AlgorithmisInside(p1, p2, p3, p)Input: Three points of a triangle, the point p to check.Output: True, when ... Read More
When you use a Text join in SAP HANA, following condition should be met −You should have Text table always on the right side in joinThere should be a Language columns definedBelow shows an example of Attribute join where Language column is used in text join −
Like other database, you can insert rows in column based table in SAP HANA using Insert statement. Insert statement can be written in SQL editor in HANA.To open SQL editor, you can select HANA system and click on SQL sign at top.Below SQL statements can be used to insert the data −INSERT INTO TEST.PROD_DESC VALUES (11, ’E’, ’Table’); INSERT INTO TEST.PROD_DESC VALUES (11, ’D’, ’Chair’); INSERT INTO TEST.PROD_DESC VALUES (14, ’E’, ’32 LED’); INSERT INTO TEST.PROD_DESC VALUES (14, ’D’, ’32 inch LCD’); INSERT INTO SAP_STUDENT.PRODUCT_DESC VALUES (25, ’E’, ’Comp Table’); INSERT INTO SAP_STUDENT.PRODUCT_DESC VALUES (25, ’E’, ’Mixer’);Read More
Secant method is also used to solve non-linear equations. This method is similar to the Newton-Raphson method, but here we do not need to find the differentiation of the function f(x). Only using f(x), we can find f’(x) numerically by using Newton’s Divide difference formula. From the Newton-Raphson formula, we know that, Now, using divide difference formula, we get, By replacing the f’(x) of Newton-Raphson formula by the new f’(x), we can find the secant formula to solve non-linear equations.Note: For this method, we need any two initial guess to start finding the root of non-linear equations.Input and OutputInput: The ...

Definite integrals can be solved using this trapezoidal rule. To integrate a function f(x) between the range a to b is basically finding the area below the curve from point x = a to x = b. To find that area, we can divide the area into n trapezoids, and the width of each trapezoid is h, so we can say that (b - a) = nh. When the number of trapezoids increases, the result of area calculation will be more accurate. To solve integrals, we will follow this formula.Here h is the width of the interval, and n is the ...

From a given set of data points, the linear regression finds an equation of straight line. The given points will follow the straight line. Using this formula, we can predict what will be the value for some other specific point, which is not present in the set currently.For solving linear regression problems using some data points, we have to follow these formulae:Here the m and c are the slope and the y-intercept respectively. Using these expressions, we can get the equation of straight line in this form: 𝑦 = 𝑚𝑥 + 𝑐.Input and OutputInput: The (x, y) coordinates of some ... Read More
Like the Trapezoidal Rule, Simpson’s 1/3rd rule is also used to find the integral value from the range a to b. The main difference between trapezoidal and the Simpson’s 1/3rd rule is, in the trapezoidal rule, the whole sections are divided into some trapezoids, but in this case, each trapezoid are also divided into two parts.For this rule, we will follow this formula:Here h is the width of the interval, and n is the number of intervals. We can find the h by using Input and OutputInput: The function f(x): (x+(1/x). The lower and upper limit: 1, 2. The number of ... Read More
Runge Kutta method is used for solving ordinary differential equations (ODE). It uses dy/dx function for x and y, and also need the initial value of y, i.e. y(0). It finds the approximate value of y for given x. For solving ODE, we have to follow these formulas:Here h is the height of the interval.Note: From these formulas, we can use first two k1 and k2 find the Runge-Kutta 2nd Order solution for ODE.Input and OutputInput: The x0 and f(x0): 0 and 0 the value of x = 0.4 the value of h = 0.1 Output: Answer of differential equation: ...

For constructing new data points within a range of a discrete set of given data point, the interpolation technique is used. Lagrange interpolation technique is one of them. When the given data points are not evenly distributed, we can use this interpolation method to find the solution. For the Lagrange interpolation, we have to follow this equation.Input and OutputInput: List of x and f(x) values. find f(3.25) x: {0, 1, 2, 3, 4, 5, 6} f(x): {0, 1, 8, 27, 64, 125, 216} Output: Result after Lagrange interpolation f(3.25) = 34.3281AlgorithmlargrangeInterpolation(x: array, fx: array, x1)Input − x array and fx ...
