\displaystyle\left\{ \begin{array}{lc} x=a(\theta-sin\theta)\\ y=a(1-cos\theta)\\ \end{array} \right.(a>0,\theta\in[0,2\pi]) 接下来,就用摆线的参数形式来解决关于摆线相关数据的求法。 注1:由于摆线以2πa为周期,以下关于摆线各种数据的计算,只考虑[0,2πa]上一拱的摆线。 注2:...

Putting all together we predict the values of sin theta/sub W/ and M/sub X/ for the minimal for SU(5) model. Through a two-step massive renormalization we get another version of the solution of the RGE's which is used to predict the value of sin theta/sub W/ and M/sub X/ for...
1: \sqrt{a^2-x^2} ,比较好的换元是令 x=asin\theta ,则 dx=acos\theta d\theta 举个例子 \int_{}^{}\frac{x^2}{(9-x^2)^{3/2}}dx ,令 x=3sin\theta ,则 dx=3cos\theta d\theta 原积分变为 \int_{}^{}tan^2\theta d\theta ,过程可以自己完成。但必须要提的是,从 \sqrt...
- 参数化点 \( P(2\cos\theta, \sin\theta) \),设直线 \( l \) 的斜率为 \( k \),联立椭圆方程求交点 \( R \); - 面积公式 \( S = \frac{1}{2} |PQ \times PR| \),转化为关于 \( \theta \) 和 \( k \) 的函数,求极值。
