Related questions Concept guides
Stage 3 · optional
Newton method for root finding
At a qualified point with nonzero derivative, Newton method moves to the tangent-line zero x−f(x)/f_prime(x); convergence requires separate local hypotheses.

Composite trapezoidal quadrature
On a strictly increasing partition, add each subinterval width times its two-endpoint average to approximate the definite integral.
Related questions Concept guides
Stage 3 · optional
Gradient descent
In fixed Euclidean coordinates, a positive step moves opposite the gradient; descent and convergence still require objective and step-size hypotheses.
Related questions Concept guides
Stage 3 · optional
Necessary Lagrange multiplier condition for equality constraints
At a regular feasible constrained local extremum, the objective gradient is a linear combination of the constraint gradients.
