Derivative of Tan x
The derivative of tan(X)
Since tan(X)=sin(X)/cos(X), we have sin(X) as the function u(X) and cos(X) as the
function v(X).
Putting these into the formula
d[uv]/dX=(vdu/dX - udv/dX)/v2
we get
d[tan(X)]/dX = (cos(X)cos(X) + sin(X)sin(X))/cos2(X)
But on the top we have sin2(X)+ cos2(X), which is always 1.
So our...

So our result simplifies to d[tan(X)]/dX = 1/cos2(X). But that is sec2(X), since sec(X)=1/cos(X). So the derivative of tan(X) is sec2(X).

Equivalence Relations Tutorcircle. com Page No. : 1/4 Equivalence Relations A relation on A is an equivalence relation if it is reflexive, symmetric and transitive. An example of such is equality on a set. One might think of equivalence as a way to glob together elements that can be considered the same relative to a property. That is elements become indistinguishable relative to the relation. For example in arithmetic we don t think twice about 1/2 and 2/4 as having the same value but they are different objects. In geometry, similarity of triangles is an equivalence relation. A right angled triangle with legs of length 3 and 4 and hypotenuse of length 5 is not the same as one with lengths 6, 8 and 10. Yet, we think of them as equivalent because the ratios of the corresponding sides are the same. For each , we define the equivalency class containing a to be the set of those elements which are equivalent to a. We denote this set by [a] although you should be aware that there

Other forms of energy is energy of height (potential energy), and heat energy. There are more. Energy can not be made or destroyed. It can only go from one form into another form.

How to Solve Mathematical Induction Tutorcircle. com Page No. : 1/4 How to Solve Mathematical Induction One of the most important tasks in mathematics is to discover and characterize regular patterns or sequences. The main mathematical tool we use to prove statements about sequences is induction. Induction is a very important tool in computer science for several reasons, one of which is the fact that a characteristic of most programs is repetition of a sequence of statements. To illustrate how induction works, imagine that you are climbing an infinitely high ladder. How do you know whether you will be able to reach an arbitrarily high rung? Suppose you make the following two assertions about your climbing abilities: 1) I can definitely reach the first rung. 2) Once I get to any rung, I can always climb to the next one up. If both statements are true, then by statement 1 you can get to the first one, and by statement 2, you can get to the second. By statement 2 again, you can

Kinetic and Potential Energy In linguistics, the potential mood The mathematical study of potentials is known as potential theory; it is the study of harmonic functions on manifolds. This mathematical formulation arises from the fact that, in physics, the scalar potential is irrotational, and thus has a vanishing Laplacian — the very definition of a harmonic function. In physics, a potential may refer to the scalar potential or to the vector potential. In either case, it is a field defined in space, from which many important physical properties may be derived. Leading examples are the gravitational potential and the electric potential, from which the motion of gravitating or electrically charged bodies may be obtained. Specific forces have associated potentials, including the Coulomb potential, the van der Waals potential, the Lennard-Jones potential and the Yukawa potential. In electrochemistry there are Galvani potential and Volta potential. In Thermodynamics potential refers

Prime number is a natural number with exactly two distinct natural number divisors: 1 and itself. Natural number is a positive integer number. Prime numbers are positive, non-zero numbers that have exactly two factors -- no more, no less. Note: There is a limit to how big of a number you can check, depending on your browser, and operating system.

Kinetic Energy Equation Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational (the energy due to motion from one location to another). To keep matters simple, we will focus upon translational kinetic energy. The amount of translational kinetic energy (from here on, the phrase kinetic energy will refer to translational kinetic energy) that an object has depends upon two variables: the mass (m) of the object and the speed (v) of the object. The following equation is used to represent the kinetic energy (KE) of an object. This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a three
