Inscribed Circles and Isosceles Triangles |
Given two real numbers
Compute to six significant decimal places
For those whose geometry and trigonometry are a bit rusty, the center of an inscribed circle is at the point of intersection of the three angular bisectors.
The input begins with a single positive integer on a line by itself
indicating the number of the cases following, each of them as described below.
This line is followed by a blank line, and there is also a blank line between
two consecutive inputs.
The input will be a single line of text containing
two positive single precision real numbers (B H) separated by
spaces.
For each test case, the output must follow the description below. The outputs
of two consecutive cases will be separated by a blank line.
The output should
be a single real number with twelve significant digits, six of which follow the
decimal point. The decimal point must be printed in column 7.
