The notation L≡RL\equiv RL≡R means both sides are equal for [ ].
A
cos2x≡2cos2x−1\cos2x\equiv2\cos^2x-1cos2x≡2cos2x−1
B
The simplified expression may be defined where the original factor was zero.
C
The notation L≡RL\equiv RL≡R means both sides are equal for every value in their common domain.
D
The more complicated side.
