As the coefficient of x^2 is not 1, we think of this equation as ax^2 +bx + c. When the coefficient of x^2 is not 1, then we need to firstly multiply the first and last numbers together (8 and -3) which g...

One landform found near convergent boundaries are coastal fold mountains. This is through the process of subduction over billions of years. This transforms island arcs (as shown in the diagram) into conti...

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[...

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...

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，...
