In mathematics there are lots of terms and definitions that are hard to remember. Trigonometry is a field of math with many hard terms to remember. However, there is a simple trick to remember the the definition of the basic trigonometric functions. With just using the simple mnemonic phrase like Soh Cah Toa, you can simplify remembering the basic trigonometric properties of the right triangle.
9. In trigonometry, the
right triangle is a very
special one with unique
properties not found in
other triangles.
Mnemonics is good
here.

Let’ s see… in every

angle. Side c is the
hypotenuse.
11. Every angle -written
