A) $x ^ { 2 }$
B) $x$
C) $2 x$
D) $1$
E) $2 \sqrt { 1 - x ^ { 2 } }$

Question

Quizplus · Accepted Answer

The expression sin(sin^(-1)x + cos^(-1)x) can be simplified using the identity sin^(-1)x + cos^(-1)x = π/2 for all x in the domain of these inverse functions. Since sin(π/2) = 1, the expression simplifies to 1.
