wandersonp Posted July 11, 2015 Share Posted July 11, 2015 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 Quote Link to comment Share on other sites More sharing options...
edward Posted July 12, 2015 Share Posted July 12, 2015 Often, inverse tangent or arctangent is more frequently used I think.
