This version is used to calculate lengths. Calculate the length BC. Give the answer to three significant figures. Use the form \(a^2 = b^2 + c^2 - 2bc \cos{A}\) to calculate the length. \(\text{BC}^2 ...

This article compares two algorithms that compute values of the sine and cosine functions using analytic geometry and the unit circle definition of sine and cosine. One algorithm uses chords on the ...
