Statement:The law of cosine states that the square of any one side of atriangleis equal to the difference between thesumof squares of the other two sides and double the product of other sides and cosine angle included between them. Let a, b, and c be the lengths of the three sides of...

Equation (4.14) is equivalent to a catchy-sounding rule: The function of an angle is equal to the corresponding cofunction of its complement. Note that cosine and sine are even and odd functions, respectively: (4.15)cos(-θ)=cosθwhilesin(-θ)=-sinθ. Whenever one of these functions ...
In this section, we make the notion of alaw smellmore precise (3.1), illustrate it via examples (3.2), and develop a taxonomy of law smells that prove particularly problematic in practice (3.3). For conciseness, we refer to the government parties involved in creating legal rules aslawmakers...
Based on the definition of TNB frame, the binormal vector is (98) (3) Reference Quaternion: Based on the rotational property, the direction cosine matrix (DCM) can be composed by , , and ; that is, (99) Applying the quaternion kinematics, the reference quaternion is (100) 4.2. ...
Simultaneously, this practice also results in the abandonment of a large quantity of high-quality coal resources, posing a serious threat to the sustainability of coal m ining4,5. Therefore, the safe and efficient extraction of residual coal pillar resources, which are abundant in reserves ...
