convert - Why I can't get correct value when used proj4js's method transform() (wgs84 -> utm-k) -


i wanna correct value transform in proj4js coordinate converted value wgs84 (epsg:4326) -> utm-k (epsg:5179)

i tried coordinate converted value couldn't correct value.

but other convert values correct.

coordinate 제주도청 in korea.

correct value : 

wgs84 (lat = 33.48900054, lon = 126.4982831) ->   utm-k (906941.5, 1500134.1)

incorrect value : 

wgs84 (lat = 33.48900054, lon = 126.4982831) ->  utm-k (5252601.193315057, 7146101.943385382)

why can't correct value when used proj4js convert wgs84 -> utm-k.

my source :

proj4js.defs["epsg:5179"] = "+proj=tmerc +lat_0=38 +lon_0=127.5 +k=0.9996 +x_0=1000000 +y_0=2000000 +ellps=grs80 +units=m +no_defs";  proj4js.defs["epsg:5186"] = "+proj=tmerc +lat_0=38 +lon_0=127 +k=1 +x_0=200000 +y_0=600000 +ellps=grs80 +units=m +no_defs";  var projwgs84 = new openlayers.projection("epsg:4326");  // projection utm-k    var projutmk = new openlayers.projection("epsg:5179");  var point_to_transform = new openlayers.lonlat(33.489219, 126.498379);  point_to_transform.transform(projwgs84, projutmk);    console.log(point_to_transform.lon, point_to_transform.lat);

or

//      var center4wms = new openlayers.lonlat(33.489219, 126.498379); //      var mapcenter = center4wms.transform(projwgs84, projutmk); //      console.log( 'mapcenter : '+mapcenter.toshortstring() );

but can correct value when convert utm-k -> wgs84 ...

anyway,result:

1: incorrect value image

sorry mistake....

i changed latitude , longitude when entered value in lonlat method.

var point_to_transform = new openlayers.lonlat(126.498379, 33.489219);

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
