2012年7月30日 · f(x-8)=f(x) 将x换成x+8 得到f(x)=f(x+8) 利用周期的定义，f(x)的周期是8

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

三角学的基础是平面三角学，研究平面上的三角形中边与角之间的关系，分为角的度量、三角函数与反三角函数、诱导公式、和与差的公式、倍角、半角公式、和差化积与积化和差公式、解三角形等内容，可能会是单独的一个科目或是在预科微积分教授，三角函数在纯数学及应用数学中的许多领域中出现，例如傅里叶分析及波函数等，是许多科技领域的基础。 三角学也包括球面三角学，研究球面上，由大圆的弧所包围成的球面三角形，位在曲率为正值常数的曲面上，是椭圆几何的 …

Example: f(x) = √x and g(x) = x 2. The Domain of f(x) = √x is all non-negative Real Numbers. The Domain of g(x) = x 2 is all the Real Numbers. The composed function is:
