The main function of meristematic tissue is to continuously form a number of new cells and help in growth. Sections through (a) stem apex and (b) root tip showing meristematic tis..

If limit of a function f exists at a point c, but it is not equal to the value of the function at c. But if f(c) l, then the function is said to have removal discontinuity at x = c. This type of function can be made continuous by charging the v..

Derivative of a Function - So far we have discussed the derivative of a function f(x) at a point 'a' which is in the domain of f. Suppose we want to find the derivative of the same function at a different point 'b', then we have to compute the deriv..

1. We say that f(x) is continuous if f(x) is continuous at every point in its domain. 2. If f and g are two continuous functions then f + g, f - g, fg are continuous functions. 3. Every polynomial function is continuous. 4. Every ratio..

A function f(x) is said to be differentiable at a point 'a' if (i) both Rf '(a) and Lf '(a) exists and finite. (ii) Rf '(a) = Lf '(..

A function f (x) is said to be continuous at x = a ifA function f (x) is said to be continuous at x = a if f (a) exist..

A function is said to be monotonic if it is either increasing or decreasing but not both in a given interval. Consider the function The given function is increasing function on R. Therefore it is a monotonic function in [0,1]. It has its minimum ..

The minimum amount of energy required to emit electrons from a metal surface is called the work function or threshold energy of that metal. The number of electrons emitted per second i.e. the rate of emission depends upon the material of the surface temperature of the surface area..

Points to Remember - Cell is the structural and functional unit of life. The direction in which water flows from one cell to another cell depends on the water potential. Two factors which affect the water potential are the amount of solutes and the external pressure. Due to endo..

The points of intersection with x-axis is determined by letting y = 0. Putting y = 0, - sin 2x = 0 This implies the curve intersects the x-axis at the points where The points at which the tangent is parallel to x-axes are determined by solving. y = - sin 2x ..
