derecho! Pero todavía los parámetros de entrada son ProcJobLocation.bearing (53.944592, 27.595215, 55.745752, 37.630768); y la salida es 359.11592632310266. Todavía hay un error. –
Sus entradas parecen estar en grados. Necesita convertirlos a radianes usando 'Math.toRadians()', de lo contrario 'Math.sin()', 'Math.cos()' etc dará resultados incorrectos. – DNA
