Hello
I noticed you mentioned SOHCATOA but didn’t like to how do we memorise them, I suggest we could add this as an appropriate link https://www.teachoo.com/5224/950/What-are-sin-cos-tan—-How-to-memorise-them/category/Trignometric-Ratios/

The trigonometric functions are periodic, with a period of 360 degrees or 2? radians.
NO – the tan function has a period of pi radians.

Thank you, Stephen, for your comment.
You are correct, the tangent and cotangent have a period of pi radians, not 2 pi.
That error will be corrected.
