Cosine Ratios
This video explains how cosine ratios, along with sine and tangent ratios, are ratios of two different sides of a right triangle. Cosine ratios are specifically the ratio of the side adjacent to the represented base angle over the hypotenuse. In order to find the measure of the angle, we must understand inverse trigonometric functions. (2:03)

Everyday experience teaches us that unconfined objects are free to move in three independent directions. I can move my hand up or down, left or right, backwards or forwards. By combining movements in these three directions I can, at least in principle, move my hand to any point in space. The fact that there are just three independent directions, and that these suffice to reach any point, shows that the space in which my hand moves is three-dimensional.

The motion of a large objec

AB InBevâ€™s Acquisition Formula
The beer giant applies three core principles to swallowing its competitors.
Author(s): Laurence Capron, INSEAD Professor of Strategy

Fresh water is becoming increasingly scarce, as climate change and population growth puts greater pressure on resources. But the problem is one of mismanagement, rather than supply. When Jair Bolsonaro was sworn in as Brazilâ€™s president in January, he spoke of a national effort to fix the countryâ€™s economy and to tackle crime and corruption. Can he deliver on those promises? And how a big-budget Chinese film reflects the philosophy of the countryâ€™s leader.

You have seen that two kinds of active galaxies - quasars and radio galaxies - are often seen to possess narrow features called jets projecting up to several hundred kiloparsecs from their nuclei. If these are indeed streams of energetic particles flowing from the central engine, how do they fit with the accretion disc model? How could the jets be produced?

The answers to these questions are not fully resolved, but there are some aspects of the model of the central engine which probably
