Useful use of tangent function

Hey guys in my work daily I use frequently cos, sin, acos, asin, I know that dot is cossine between the given 2 vectors, and the magnitude o cross between 2 vectors is sin of angle between this 2 vectors, this stuff make a lot of sense to me right now.

 

but what I dont recognize yet is the use of tangent, in procedural and simulation stuff. I understand the graphic function but not a usefull use of that in daily work.

 

Can anyone show me simple example of the tangent function? Which I can use in real work.

 

Thanks
