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

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.
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
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
On Easter Vigil, Christians light the Easter candle on the Easter fire. This light in the darkness reminds them of what the biblical texts describe: Jesus conquered death. Author: ZDF/Church and Life Kath./Karoline Knop/Bettina Reich/Maximilian Mohr Translation and dubbing: alugha Click here to w
Triangles are the building blocks of all other straight-edged shapes. They were used for hundreds of years to create accurate maps and GPS today still works using trigonometry. Even the pixels on phones and screens use trigonometry.We need to know these things so that we can work out exact length
There are dozens of species of canids commonly known as "fox". Some are considered "true" foxes while others are classified in other groups. These animals are cat-like in their shape with pointy ears and whiskers but also in their abilities because they can see well in the dark and some even climb t
