Inverse Trigonometry Integrals
Derivative and Antiderivatives that Deal with the Inverse Trigonometry We know the following to be true: This shows the following indefinite integral: But, what if the value in the square root is not 1? Can we still use this antiderivative?
Derivative and Antiderivatives that Deal with the Inverse Trigonometry Investigate the following: This shows the following indefinite integral: Now investigate arccos(x).
Derivative and Antiderivatives that Deal with the Inverse Trigonometry Investigate the following: This shows the following indefinite integral: This only differs by a minus sign from arcsin(x). It will be omitted from our list.
Derivative and Antiderivatives that Deal with the Inverse Trigonometry Investigate the following: This shows the following indefinite integral: Arccot(x) will only differs by a minus sign from this. It will be omitted from our list.
Integrals Involving Inverse Trigonometric Functions If u(x) is a differentiable function and a > 0, then Arcsec(x) is challenging to prove due to sign changes.
