The branches of the inverse trigonometric functions are chosen so that they are continuous. See §22.16(i) for .
Again, the branches of the inverse trigonometric functions must be continuous.
Thirdly, with ,
Lastly, with ,
For alternative, and symmetric, formulations of the results in this subsection see Carlson (2006a).
See §22.16(ii). The indefinite integral of the 3rd power of a Jacobian function can be expressed as an elementary function of Jacobian functions and a product of Jacobian functions. The indefinite integral of a 4th power can be expressed as a complete elliptic integral, a polynomial in Jacobian functions, and the integration variable. See Lawden (1989, pp. 87–88). See also Gradshteyn and Ryzhik (2000, pp. 618–619) and Carlson (2006a).
For indefinite integrals of squares and products of even powers of Jacobian functions in terms of symmetric elliptic integrals, see Carlson (2006b).
Corresponding results for the subsidiary functions follow by subtraction; compare (22.2.10).
