Before proceeding to that, however, we will consider some elementary notions and terms connected with an angle. One of the most readable books that seems to cover the topics very well is: This book serves, to me, much like a glossary. The sine of ∠B in the triangle above is the side opposite ∠B over the hypotenuse: The sine of ∠C in the triangle above is the side opposite ∠C over the hypotenuse: The cosine of ∠B in the triangle above is the line adjacent to ∠B over the hypotenuse. In other words, the quantity he found for the seked is the cotangent of the angle to the base of the pyramid and its face. [8] The earliest use of sine appears in the Sulba Sutras written in ancient India from the 8th century BC to the 6th century BC, which correctly computes the sine of π /4 (45 ° ) as 1/√2 in a procedure for circling the square (the opposite of squaring the circle ), though they had not yet developed the notion of a sine in a general sense. [9] The chord of an angle subtends the arc of the angle.
