Answer
Explanation:
Step1: Evaluate $\tan^{-1}1$
We know that $\tan^{-1}1=\frac{\pi}{4}$. So the equation $\sin^{-1}x - \tan^{-1}1=-\frac{\pi}{3}$ becomes $\sin^{-1}x-\frac{\pi}{4}=-\frac{\pi}{3}$.
Step2: Isolate $\sin^{-1}x$
Add $\frac{\pi}{4}$ to both sides of the equation: $\sin^{-1}x=-\frac{\pi}{3}+\frac{\pi}{4}$.
Step3: Calculate the right - hand side
Find a common denominator. $-\frac{\pi}{3}+\frac{\pi}{4}=\frac{-4\pi + 3\pi}{12}=-\frac{\pi}{12}$. So $\sin^{-1}x=-\frac{\pi}{12}$.
Step4: Solve for $x$
Take the sine of both sides. $x = \sin(-\frac{\pi}{12})$. Since $\sin(-\alpha)=-\sin\alpha$, then $x=-\sin\frac{\pi}{12}$. And $\sin\frac{\pi}{12}=\frac{\sqrt{6}-\sqrt{2}}{4}$, so $x =-\frac{\sqrt{6}-\sqrt{2}}{4}=\frac{-\sqrt{6}+\sqrt{2}}{4}$.
Answer:
A. $\left{\frac{-\sqrt{6}+\sqrt{2}}{4}\right}$
