The integration of tanx gives us ln|secx|+c. Furthermore, we will also see the derivation of the integral of tanx.

A straight line is basically just a line with no curves. Usually, when we speak about lines, we are talking about straight lines. Furthermore, here we are going to learn about different forms of equation of straight line.

Xylem and phloem together forms the vascular system of plants. They perform the same function of transportation but they are different in many ways. Let us learn how.

Wheatstone bridge is a circuit which have two or more branches such that no current flows from resistance branch joining main branches.

Power of lens mathematically is the inverse of focal length. One dioptre is the measure of convergence or divergence by a lens of focal length 1 meter.

Section formula is basically used to find the coordinates of the point that divides the line segment into any ratio. Read more about the section formula and its examples in the following section.

The human excretory system consists of a complex tubular structure inside its two bean shaped kidneys. In this blog, we will be understanding the structure of nephrons and its type.

Arithmetic Progression (A.P) is a sequence of numbers where the difference between any two successive numbers is constant. Read here more about A.P and its formulas.

Lens maker formula gives relation between refractive index, focal length, and radius of curvature for any lens. Read more about it below.

This article have two methods of derivation of lens formula. One is similar triangle method and other is refraction through curved surface. First one is used in 10th class and second one is used in 12th class. Scroll down to see both separately.

This blog discusses how conditional probability is defined and also in what ways it is useful. Few solved problems are presented for better understanding of the viewer.

Translatory motion is the motion in which every point on the moving body moves through the same distance in the same interval of time.
