„The development of Indian trigonometry, based on sine as against chord of the Greeks, a necessity for astronomical calculations with his own concise notation which expresses the full sine table in just one couplet for easy remembrance. One of the two methods suggested by him for the sine table is based on the property that the second order sine differences were proportional to sines themselves.“

Contesto: In any age courage is the simple virtue needed for a human being to traverse the rocky road from infancy to maturity of personality. But in an age of anxiety, an age of her morality and personal isolation, courage is a sine qua non.
