Label:Trigonometric Correlation Types1. Using triangular changes and trigonometric identities, such as $\sin^2 x + \cos^2 x=1$ and twice-fold formula, and differential product, accumulation and difference.For example: 4-1 of 1-(5), so that $1=\sin^2

Label:1. Set the known $ \sum\limits_{n = 1}^\infty {{{\left ({-1} \right)}^{n-1}}{a_n}} = A,\sum\limits_{n = 1}^\infty {{a_{2n-1 }}} = B $, proof: $ \sum\limits_{n = 1}^\infty {{A_n}} $ converge and ask for and.Solution: There is

Label:Description 反正切函数可展开成无穷级数，有如下公式 (其中0 <= x <= 1) 公式(1) 使用反正切函数计算PI是一种常用的方法。例如，最简单的计算PI的方法： PI=4arctan(1)=4(1-1/3+1/5-1/7+1/9-1/11+...) 公式(2) 然而，这种方法的效率很低，但我们可以根据角度和的正切函数公式： tan(a+b)=[tan(a)+tan(b)]/[1-tan(a)*tan(b)]

Label:(1)\[\begin{aligned}\int \frac{x}{x^2+2x-3}dx= \int \frac{x-1+1}{(x+3) (x-1)}DX= \int \frac{1}{x+3} + \frac14 \frac{4}{(x+3) (x-1)} DX\\=\int \frac{1}{x+3} + \frac14 \frac{(x+3)-(X-1)} {(x+3) (x-1)} DX= \int \frac{3/4}{x+3}-+ \frac{1/4}{x-1}
