WebThe general trigonometric form of complex numbers is r ( cos θ + i sin θ). From the graph, we can see how the trigonometric or polar forms of complex numbers were derived. Since a = r cos θ and b = r sin θ, a + b i = r ( cos θ + i sin θ). From this, r represents the modulus and θ shows the angle (or the argument) formed by r and the real ... WebSep 15, 2024 · Theorem. Let a and b be real numbers . Let i be the imaginary unit . Then: sinh(a + bi) = sinhacosb + icoshasinb. where: sin denotes the real sine function. cos denotes the real cosine function. sinh denotes the hyperbolic sine function.
