应网友之约,讲解一些典型的有理函数的不定积分计划分4个视频,讲解 ∫1/(x^3+1) dx,∫1/(x^4+1) dx,∫1/(x^5+1) dx,∫1/(x^6+1) dx 这4个有理函数的不定积分。有理函数不定积分的一般计算方法,在这写不下,有兴趣的朋友可去我的动态查看。视频中用到的sin18°,cos36°
Aims: We investigate the X-ray spectral and timing properties of the accreting X-ray pulsar Her X-1 observed with the INTEGRAL satellite in July-August 2005. Methods: The data analyzed in this work cover a substantial part of one main-on state of the source. The short-time scale pulse ...

Recent results of the spectral and timing analysis of X-ray pulsars in hard X-rays with the INTEGRAL observatory are reviewed. The evolution of the cyclotron line energy with the source luminosity was studied in detail for the first time for several sources. It was shown that for V0332+53 ...

Integrate[1/x^2,{x,-1,1}]结果显示Integral of 1/x^2 does not converge on {-1,1}.我当然知道1/0是无穷,但是这软件算不出来,就把原来的式子重新给我写了一遍,而不是无穷哪个符号,没有结果。还输出了 Integral of 1/x^2 does not converge on {-1,1}....
