Equation of plane and applications
A plane is determined by a point P in the plane and a normal vector n perpendicular to the plane. Since each vector in the plane must be orthogonal to the normal vector n. Equations is called a vector equation of the plane. Vector equation of a plane. a plane may be characterized by a point contained in the plane and a vector that is perpendicular, or normal, to the plane. Therefore equation plane also called cartesian equation. Plane […]
Trigonometric Equation
Solving trig equations use both the reference angles and trigonometric identities The general method of solving an equation is to convert it into the form of one ratio only. Then, using these results, hence, we can obtain solutions. Trigonometric equation
Binomial distributions
This post is about binomial distributions. The Binomial distribution has two parameters like n and p. Due to n and p it is binomial. these n and p are n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiment. Also we use probability of failure. Binomial
Vector and vector equation of line
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 […]

Equation of line
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
