New AnswerPI is the constant 3.14 (most common estimate) that represents the ratio of a circle's circumference to its diameter. in simpler terms you need 3 of a cirlce diameter to make a new cirlce that big and .14 in length of the diameter to complete it as 3 of the diameters cannot make the whole circle check out: https://youtu.be/cC0fZ_lkFpQ as for tan and sin, these are trigonometric functions

your top question is not clear and the tag 'me' is irrelevant, please read this post https://www.sololearn.com/discuss/1316935/?ref=app

Lexfuturorum i understand that part but the top question 'JS' is unclear

And befor I give you the second answer I have to know. Did you finish school already?

Mind To Machine ðŸ’»ðŸ•† he wants to know about sinuous, cosenuos and tangent And tere uses in web development. Pretty clear question for me

Drawing something in real time happens with Javascript he probably heard about that this way and if you want to draw a triangle just with the length of the sides you need to use these tree functions.
