Abstract : basing on the introduction of brim - vector and face - vector, by means of analogy, the paper popularizes the cosine - theorem from flat - triangle to vacuum - polygon and arbitrary - polyhedron, concludes a series of generalized cosine - theorems which have symmetric and conformable form, and presents short and strict proof
文摘:在引入邊矢量及面矢量概念的基礎上,以類比作為手段,對餘弦定理進行由平面三角形到空間多邊形乃至任意多面體的一系列推廣,得出了形式對稱一致的一組廣義餘弦定理,並給出了其簡捷嚴謹的證明。Through analyzing the choice of the personal behavior dynamically and balancedly, including psychological direction, ability direction and professional direction, that is when these three directions are completely consistent, people ’ s planned ability desire and the realisation proportion of the job will achieve the greatest. this is a process of unceasingly enhancing the determined resources to meet the rate needs ? enhancing the cosine value of the angles with two directions, thus is also named the theory of cosine equilibrium
通過對個人行為方向性選擇的心理方向、能力方向和職業方向進行動態平衡分析,即在行為人的心理方向、能力方向和職業方向三個方向達到完全一致時人們既定的能力願意而且能夠用於工作的比例就達到最大,這個動態過程是一個不斷提高既定資源用來滿足需要的比例? ?即提高兩個方向夾角的餘弦值的過程,因此把這個動態平衡的選擇過程稱作餘弦均衡。
