Practice problem
Simplify sin(2sin−1(x))\sin(2\sin^{-1}(x))sin(2sin−1(x)) without the use of inverse trigonometric functions.
2x2x2x
2x1−x22x\sqrt{1-x^2}2x1−x2
2xx2−12x\sqrt{x^2-1}2xx2−1
2x1−x2\frac{2x}{\sqrt{1-x^2}}1−x22x
2xx2−1\frac{2x}{\sqrt{x^2-1}}x2−12x
Type a concept, like “slope” or “photosynthesis”.
