Trigonometry
In trigonometry, you will learn about sines, cosines and tangents and how in a right angled triangle you can find the sine, cosine or tangent of any of its angles by working out the ratios of the lengths of two of the triangles sides. This means that:
Opposite /(over) Adjacent = Tan
Opposite /(over) Hypotenuse = Sine
Adjacent /(over) Hypotenuse = Cosine
To remember this just learn the following phrase:
One Ancient Teacher
Of History Swore
At His Class
My thanks to James Banks for sharing that with us.
