Sorry for the mangled output, this should be better: cot *A* = 1 / (tan *A*)
sec *A* = 1 / (cos *A*) csc *A* = 1 / (sin *A*) @Don The inverses are the arc functions and have different definitiions On Tue, Aug 15, 2017 at 1:12 PM, Don Guinn <[email protected]> wrote: > Negative left number gives inverses. > > 1 o.1 > 0.841471 > _1 o.1 > 1.5708 > _1 o. 1 o. 1 > 1 > > On Tue, Aug 15, 2017 at 11:01 AM, Raul Miller <[email protected]> > wrote: > > > Which rows are cotangent, secant and cosecant? > > > > (I see sine, cosine, tangent, square root, hyperbolic sine and > > hyperbolic cosine.) > > > > Thanks, > > > > -- > > Raul > > > > > > On Tue, Aug 15, 2017 at 12:41 PM, Linda Alvord <[email protected]> > > wrote: > > > > > > > > > Sent from AOL Mobile Mail > > > > > > > > > From: Linda Alvord <[email protected]> > > > Date: Tuesday, August 15, 2017 > > > Subject: FW: why are there no negative signs for cot,sec and csc? > > > Cc: lindaalvord <[email protected]> > > > > > >  > > > > > > > > > > > > > > > > > > From: Linda Alvord [mailto:[email protected]] > > > Sent: Tuesday, August 15, 2017 11:22 AM > > > To: '[email protected]' <[email protected]> > > > Subject: why are there no negative signs for cot,sec and csc? > > > > > > > > > > > > do=: 13 : '({.y) +(i.{:y)*(--/ 2{.y)%<:{:y' > > > > > > t=:do 0 2p1 17 > > > > > > all=:1 2 3 4 5 6 (o."0 1) t > > > > > > *all > > > > > > 0 1 1 1 1 1 1 1 0 _1 _1 _1 _1 _1 _1 _1 0 > > > > > > 1 1 1 1 0 _1 _1 _1 _1 _1 _1 _1 0 1 1 1 1 > > > > > > 0 1 1 1 1 _1 _1 _1 0 1 1 1 1 _1 _1 _1 0 > > > > > > 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 > > > > > > 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 > > > > > > 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 > > > > > > > > > > > > Linda > > > > > > ---------------------------------------------------------------------- > > > For information about J forums see http://www.jsoftware.com/forums.htm > > ---------------------------------------------------------------------- > > For information about J forums see http://www.jsoftware.com/forums.htm > > > ---------------------------------------------------------------------- > For information about J forums see http://www.jsoftware.com/forums.htm > ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
