The vector is direction one point to another point. The vector equation of a line is r = a + tb. In this equation, “a” represents position vector and “b” represents a direction vector of the line. Moreover “r” represents the vector of any general point on the line and “t” is constant. Hence it is similar to equation of line vector
Normal Distribution
A graphical representation of a normal distributions are sometimes called a bell curve because of its flared shape. The precise shape can vary according to the distribution of the population but the peak is always in the middle and the curve is always symmetrical. In a normal distribution, the mean, mode and median are all the same. The Normal distribution has two […]

Maxima and minima
A high point of curve is called a maxima. A low point is called a minima. In the Curve only one global maxima or minima exists , while more than one local maximum or minimum. Due to curve turn on these point are called local. Hence these point also called stationary points. Maxima and minima
Equation of curve
Equations of curve evaluate by doing integration of derivative curve. The gradient and a point the curve passes through are given as.. Gradient: dy/dx = 6sqrt(x) Point the curve passes through: (4,1) I need to find the equation of the curve. Therefore integration is process of finding equation of the curve. Equation of curve
Binomial Theorem
When a binomial is raised to whole number powers, the coefficients of the terms in the expansion form a pattern. Each expansion has one more term than the power on the binomial. The sum of the exponents in each term in the expansion is the same as the power on the binomial. www.kutasoftware.com
Parametric Equation
Parametric Equation. Namely, x = f ( t ), y = g ( t ) t D. where D is a set of real numbers. The variable t is called a parameter and the relations between x, y and t are called parametric equations. The set D is called the domain of f and g and it […]
Derivative of Parametric and Polar Equat...
This post is about derivatives of Polar and parametric Equations. Because of polar equation, Polar equation like parametric equations of the curve where the angle θ is parameter. As well as equations have parameter (r,θ). For this polar equation, the parametric equations are x ( θ) = cos θ and y ( θ) = sin θ. Therefore, the […]
