The derivative of a function describes the function's instantaneous rate of change at a certain point. Another common interpretation is that the derivative gives us the slope of the line tangent to the …

Explore AP Calculus AB differentiation topics with Khan Academy's free resources, including videos and practice exercises for effective learning.

Certain ideas in physics require the prior knowledge of differentiation. The big idea of differential calculus is the concept of the derivative, which essentially gives us the rate of change of a quantity …

The chain rule tells us how to find the derivative of a composite function. This is an exceptionally useful rule, as it opens up a whole world of functions (and equations!) we can now differentiate. Also learn …

Using classical physics to calculate the energy of electrons in Bohr model. Solving for energy of ground state and more generally for level n.

Magnetic fields are extremely useful. The magnetic field of the Earth shields us from harmful radiation from the Sun, magnetic fields allow us to diagnose medical problems using an MRI, and magnetic …

Circuits make computers, digital cameras, and video games possible. Circuits are driving an unprecedented rate of change in how we live. In this topic you'll learn about the physics behind the …

Oups. Il y a eu un problème. S'il vous plaît, veuillez reessayer. Oups, on dirait qu'il y a eu une erreur ! Vous devez actualiser. Si le problème persiste, dites-nous.

Light waves can be bent and reflected to form new and sometimes altered images. Understanding how light rays can be manipulated allows us to create better contact lenses, fiber optic cables, and high …
