Hello, I need to write a conclusion for my math assignment report. But i never did it before, I wan to ask that how we consider t=30/cos Ө as?
is it an equation? or?
Any of those is correct. Because is says one side = another, it is an "equation".
Because you can use it to find one value given another, it is a "formula".
Because you can think of a value of giving a value of t, it is a "function".
For your purposes, probably "formula" is best.
