(1+sinx) (1-sinx)=-x+2tanx+2 cosx+ is the integral constant.

The process is as follows:

1+sinx)/（1-sinx）=-1-sinx-2)/(1-sinx)

1+2/(1-sinx)

1+2(1+sinx)/cos^2x

1+2sec^2x+2sinx/cos^2x

Original = (1+2sec 2x+2sinx cos 2x)dx

x+2tanx-∫2/cos^2x)d(cosx)

x+2tanx-2[1/(-2+1)/cosx+c

x+2tanx+2/cosx+c

Basic introduction. The impetus for the development of integration comes from the needs of practical applications. In practice, it is sometimes possible to estimate some unknown quantities in a rough way, but with the development of technology, many times it is necessary to know the exact values.

If you want the area or volume of a simple geometry, you can apply a known formula. For example, the volume of a rectangular swimming pool can be found by length, width and height.

However, if the limb of the swimming pool is oval, parabolic, or more fissured and irregularly shaped, you need to use integrals to find the volume. In physics, it is often necessary to know the cumulative effect of one physical quantity (e.g., displacement) on another physical quantity (e.g., force), and this is also the case when integrals are used.
