Around one million people use tanning beds each year in the US. Yet the ultraviolet (UV) light they use causes skin cancer. The risk is so high that a recent article from researchers at the University of Michigan called for an immediate ban on the use of commercial indoor tanning by minors, and th
You should already know what a straight line, quadratic, cubic and reciprocal look like when plotted on a graph. In this video we will discover what the sin, cos and tan graphs look like and also exponential functions. You don't necessarily need to know the exact values that these functions cros

The Y chromosome is always transferred directly from father to son, almost unchanged. If a mutation occurs, it is passed on to all subsequent generations. Author: ZDF/Terra X/Tobias Schultes/Albrecht M. Wendlandt Translation and Dubbing: alugha Click here to see more videos: https://alugha.com/Te
Not every triangle is a right-angle triangle, so we can't always use Pythagoras and SOHCAHTOA to find missing sides and missing angles. We instead use the sine rule or the cosine rule. They can both be used to find either missing sides or missing angles in any triangle (right angle or not). Click h
SOHCAHTOA, Pythagoras, sine rule and cosine rule and all things trigonometry actually have a lot of uses in “real life”. Such as working out distances to things, heights of buildings and mountains, navigation at sea. An important part of “useful” trigonometry are angles of elevation and depression.
There are some key angles that have exact values in trigonometry. The ones we need to know are 0, 30, 45, 60 and 90. In this video we will discover one method of remember what these values are - using a table. In the second part we will discover a different method (using our fingers) which you may p

Hemophilia patients lack an important element in the complex process of blood clotting. As a result, blood from wounds does not clot or clots only very slowly. Even minor injuries can become a health hazard to the patient. Wang Xia Li from Beijing talks about how she and her sick son deal with the d
