Setting displaystylevarphi=pi in Euler's formula results in Euler's identity, celebrated in mathematics due to it containing five important mathematical constants: displaystyleeⁱᵖⁱ+1=0. There are n different complex numbers z satisfying displaystylezⁿ=1, and these are called the "n-th...
Continuing, we may disable '/' to get a trignometric identity involving pi/4; disabling the trig functions as well, the command becomes ries 1.4142136 '-Nsˆq*Lv/ASCT' and we finally get an answer that most people probably would not guess: x-1/(x+1) = 1 (note that the '/' in...
Evaluated at z = 1/2 and squared, the equation Γ(1/2)² = π reduces to the Wallis product formula. The gamma function is also connected to the Riemann zeta function and identities for the functional determinant, in which the constant π plays an important role. The gamma function is...
