Java Utililty Methods cos

double cos(double a)
Returns the trigonometric cosine of an angle.

return Math.cos(a);

double cos(double anAngle)
Returns the cos of the given angle in degrees.

return Math.cos(Math.toRadians(anAngle));

double cos(double d)
cos

return SIN_TABLE[(int) ((float) d * 10430.378F + 16384.0F) & 65535];

double cos(double radians)
Get the cosine of an angle

return sin(radians + Math.PI / 2);

double cos(double[] v1, double[] v2)
cos

double s = 0;
s = multiple(v1, v2);
double a = Math.pow(multiple(v1, v1) * multiple(v2, v2), 0.5);
return s / a;

double cos(double[] v1, double[] v2)
cos

double s = 0;
s = Math.abs(multiple(v1, v2));
double a = Math.pow(multiple(v1, v1) * multiple(v2, v2), 0.5);
if (a == 0) {
 return -1.0;
return s / a;

double cos(final double value)
cos

final int temp;
if (value > 0) {
 if ((int) value > 360d) {
 if ((temp = ((int) value - ((int) (value / 360d)) * 360)) != 0) {
 return (double) COS_TABLE[temp];
 } else {
 return (double) COS_TABLE[360];
 } else {
 return (double) COS_TABLE[(int) (value)];
} else if ((-(int) value) > 360d) {
 if ((temp = (-((int) value - ((int) (value / 360d)) * 360))) != 0) {
 return (double) COS_TABLE[temp];
 } else {
 return (double) COS_TABLE[360];
} else {
 return (double) COS_TABLE[-(int) (value)];

float cos(final float angle)
Faster cos method using special cache, based on Mojang code.

return sinCache[((int) ((angle * UNKNOWN_CONST) + ((SIN_CACHE_SIZE + 1) / 4)) & SIN_CACHE_SIZE)];

float cos(final float value)
cos looked up in the sin table with the appropriate offset

return SIN_TABLE[(int) (value * 10430.378F + 16384.0F) & 65535];

float cos(float angle)
cos

return (float) Math.cos(angle);
