Examples
Code Editor (JavaScript)
print('Trigamma for -100', ee.Number(-100).trigamma()); // Infinity
print('Trigamma for 0.001', ee.Number(0.001).trigamma()); // 1000001.642533195
print('Trigamma for 0.5', ee.Number(0.5).trigamma()); // 4.934802200
print('Trigamma for 1', ee.Number(1).trigamma()); // 1.644934066
print('Trigamma for 100', ee.Number(100).trigamma()); // 0.010050166
print('Trigamma for 200', ee.Number(200).trigamma()); // 0.005012520
