Marginal Cost and Revenue

"The marginal cost and marginal revenue are the additional amount of cost or revenue that arise from producing one more item. If you take the derivative of the cost and revenue functions, you get appr ...

Approximate Area

"When finding the area under a curve for a region, it is often easiest to approximate area using a summation series. This approximation is a summation of areas of rectangles. The rectangles can be eit ...

Magnetic Fields

"Magnetic fields are vector fields associated with magnetic forces. Magnetic fields are generated by Hard Ferromagnets. Unlike electric fields, magnetic fields always make closed loops and are never c ...

Applications of Linear Equations

"We often see math applied to the real world through word problems, and the applications of linear equations are seen throughout all our math courses after Algebra. To understand applications of linea ...

Magnetic Domains

"Magnetic domains are collections of magnetic fields in the same direction. They are often found in ferromagnetic materials because their atoms align with magnetic fields in a process called a ferroma ...

Antidifferentiation

"Finding the antiderivatives of a function require a little backwards thinking. Since the derivative of the wanted antiderivative is the given function, checking for correctness is easy. You just take ...

Lorentz Force

"Lorentz force is the force on charge in electromagnetic field. Lorentz force is determined by the formula F = qv x B, in which q is the charge, v is the velocity, and B is the magnetic field density. ...

Antiderivatives

"Antiderivatives are the opposite of derivatives. An antiderivative is a function that reverses what the derivative does. One function has many antiderivatives, but they all take the form of a functio ...

Longitudinal Waves

"Longitudinal waves are waves which move particles in the direction of the wave motion. They are the counterparts to transverse waves which move particles parallel to the direction of wave motion.  " ...

Annulus Area

Hipervinculo Matemáticas

Annulus Area

"An annulus is similar to a ring or a castle's moat; it is the area between two concentric circles. Calculating the annulus area, therefore, involves finding the difference of the two circles' area. ...
