The focal ratio theorem of the conical curve was a theorem related to the polar coordinate equation of the conical curve. According to the given polar coordinate equation of the conical curve, p =ep/(1-e* cos0), and the straight line, 0 =c or 0 = Pi +c, where c is a constant, the focal ratio theorem can be derived as:| 1-e*cosc)/(1+e*cosc)|.The specific derivation process is as follows: Consider the intersection of the conical curve and the straight line. The coordinates of the intersection are (ep/(1-e*cosc), c) and (ep/(1+e*cosc), Pi +c). According to the definition of focal radius, the focal radius length was the distance from the focal point to the intersection point. Therefore, the ratio of focal radius to length is| 1-e*cosc)/(1+e*cosc)|.This was the derivation process of the focal ratio theorem for conical curves.

Cardin's theorem

Cardin's theorem was proposed by the famous French entrepreneur Pierre Cardin. The theorem pointed out that one plus one was not equal to two in terms of employment, and sometimes it might even be equal to zero. This meant the importance and effectiveness of cooperation. An effective cooperation could break through the effect of quantity stacking. In other words, one plus one could not only be equal to two, but it could also be greater than two. However, an ineffective combination could reduce all efforts to nothing. Therefore, companies needed to consider a reasonable combination when allocating talents, so that the members could complement each other and cooperate with each other, give full play to their respective advantages, and achieve effective cooperation.

Hot and boiling hot become the focal point

"Hot and Spicy" became the focus of the Spring Festival and achieved outstanding box office performance. The movie's cumulative box office had already exceeded 2.3 billion yuan, and the final box office was expected to exceed 4 billion yuan. This result was undoubtedly a huge piece of good news for the listed companies involved in the production and distribution of the film. The female audience became the main force of the Spring Festival, and the market was clearly sinking. The data showed that female audiences accounted for more than 60% of the Spring Festival. At the same time, the box office share of third-tier and fourth-tier cities continued to rise. In addition, the success of " Hot and Spicy " also led to a craze in the fitness economy, triggering heated discussions on topics such as fitness, boxing, weight loss, and health. As the director and lead actor, Jia Ling used her own weight-loss story and the true feelings of the movie to redefine the concepts of "success" and "winning" and became the focus of the audience.
