y = x x , by taking logs:ln(y) = ln(x x )By log laws:ln(y) = xln(x)From implicit differentiation; d/dx = y'*d/dy, so:d/dx[ln(y)] = y'*d/dy[ln(y)] = y' * 1/yFrom the product rule; d/dx[xln(x)] = ln(x) * d/dx(...

Algebra is fundamentally the way in which we can find out the value of some unknown element. So for example, if a salesman agrees to sell two apples for £10 algebra can help us find out how much one apple wo...

文化多样性的重要现在很显然。如果世界的人都互相学习，互相了解，我们能达到完全文化融合。如果想建功立业，一定要关注文化融合的4个部分。尊重、接受、了解、和学习。由于中国的金融增速发展和全球地址的上升，所以中国跟西洋的关系非常重要。 虽然这幅图片比较近期，但是中国并西方国家的发展已经有30多年的历史。自从1978年，邓小平创办了中国的“改革开放”，让国外的人更容易地学习中国。 38年之后，他的计划不但非常有效，而且...
