To expand an expression using the distributive property, multiply each term inside a set of parentheses by each term outside the parentheses, and then simplify by combining like terms. The FOIL method is a mnemonic used to help remember the steps for multiplying two binomials.

f(x)=x^3 ; prove\:\tan^2(x)-\sin^2(x)=\tan^2(x)\sin^2(x) \frac{d}{dx}(\frac{3x+9}{2-x}) (\sin^2(\theta))' \sin(120) \lim _{x\to 0}(x\ln (x)) \int e^x\cos (x)dx \int_{0}^{\pi}\sin(x)dx

首先p (x;y）是一个关于y的函数，y是自变量。 这是参数估计中常用到的 似然函数，意思用变量y表示随机变量x (这里是小x，表示现在随机变量大X已经取了一个确定的值就是x)发生的概率. 更详细的解释可以参考我的博客 blog.csdn.net/sabrinalx. p (x; y) 表示y是变量. 可以理解为 p (x; y) 是一个以y为变量的函数. 很多论文都使用记号p (x;theta)或p (x;D)等 (D表示数据集)，没有见到记号解释。 例如周志华西瓜书p38也使用了…
