Don't want to work today ... But I'm going to finish today's mission.2. (1) Solution: function $y =e^{\arctan x}$ on the definition field $ (-\infty,+\infty) $ on a continuous, and\[Y ' = E^{\arctan x} \frac{1}{1+x^2}, \qquadY ' = E^{\arctan x}

(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} DX=

JavaScript: Use atan2 to draw arrows and curves, and use javascriptatan2 Recently, I am engaged in Canvas plotting and know that JavaScript provides a trigonometric function such as atan2 (y, x. At first glance, I don't know. After all, the

To do a panoramic view, of course, first look for a panoramic picture (360° fisheye lens) and then panoramic view of the conversion software, if you can do it yourself. Recommended here PANO2VR After the picture is converted, a set of cube patches

I did not expect so many limitations on the calculation of latitude and longitude in the J2EE today. Even a few simple trigonometric functions are not completely provided, and I need to write them directly. no way. Do it yourself. leave a code for
