  • Equação 1: Equação de Navier-Stokes \[ \rho \left( \frac{\partial \mathbf{u}}{\partial t} + \mathbf{u} \cdot \nabla \mathbf{u} \right) = -\nabla p + \mu \nabla^2 \mathbf{u} + \mathbf{f} \]

  • Equação 2: Equações de Maxwell

\[ \nabla \cdot \mathbf{E} = \frac{\rho}{\epsilon_0}, \quad \nabla \cdot \mathbf{B} = 0 \] \[ \nabla \times \mathbf{E} = -\frac{\partial \mathbf{B}}{\partial t}, \quad \nabla \times \mathbf{B} = \mu_0 \mathbf{J} + \mu_0 \epsilon_0 \frac{\partial \mathbf{E}}{\partial t} \]

  • Equação 3: Teorema de Bayes

\[ P(A|B) = \frac{P(B|A) P(A)}{P(B)} \]

  • Equação 4: Equação da Onda

\[ \frac{\partial^2 \psi}{\partial t^2} - c^2 \nabla^2 \psi = 0 \]

  • Equação 5: Função de Verossimilhança

\[ L(\theta; x) = f(x|\theta) \]
