For $x \in [-1, 1]$, the identity $\sin^{-1}x + \cos^{-1}x$ equals:
A$\pi/2$, a standard inverse-trig identity on chart
B$0$, since both are equal in the school chart here
C$\pi$, twice the standard value seen on the chart
D$\pi/4$, half of the correct identity value here
Answer & Solution
Correct answer: A. $\pi/2$, a standard inverse-trig identity on chart
$\sin^{-1}x + \cos^{-1}x = \pi/2$.
