Question
Multiple Choice The area of the region enclosed between the graph of $y=\sqrt{1-x^{4}}$ and the $x$ -axis is $\mathrm(A) 0.886(B) 1.253(C) 1.414(D) 1.571(E) 1.748
Step 1
This happens when $y=0$, so we set $y=0$ and solve for $x$: \[0=\sqrt{1-x^{4}}\] Squaring both sides gives $0=1-x^{4}$, which simplifies to $x^{4}=1$. The solutions to this equation are $x=\pm 1$. Show more…
