Mipaka ya majibu ya kinyume cha trigonometria

Kinyume cha sin na $\displaystyle \tan^{-1}$ hutoa daima jibu kati ya $\displaystyle -90^{\circ}$ na $\displaystyle 90^{\circ}$, na $\displaystyle \cos^{-1}$ kati ya $\displaystyle 0^{\circ}$ na $\displaystyle 180^{\circ}$. Kwa radiani, hiyo ni $\displaystyle -\frac{\pi}{2}$ hadi $\displaystyle \frac{\pi}{2}$, na $\displaystyle 0$ hadi $\displaystyle \pi$. Kwa gradi, $\displaystyle -100$ hadi $\displaystyle 100$, na $\displaystyle 0$ hadi $\displaystyle 200$.
