The lemniscate of Bernoulli was first conceived by Jacob Bernoulli in 1694. For example, the inverse of the lemniscate of Bernoulli is a rectangular hyperbola. When this is the lemniscate of Bernoulli. For , the hippopede corresponds to the lemniscate of Bernoulli. In this case the sinusoidal spiral is a polynomial lemniscate. The symbol resembles a geometric figure called a lemniscate. The name comes from the shape its central lemniscate takes when graphed. In algebraic geometry, a lemniscate is any of several figure-eight or -shaped curves. "Lemniscate" (2012), "Into" (2015), "Brunei" (2016) and "Opal" (2018). Hence, it will not look like a lemniscate, making the name something of a misnomer.
