Triple integral, curve and surface integral, infinite series (including Fourier series), vector algebra and spatial analytic geometry, directional derivative and gradient in differential calculus of multivariate functions, tangent plane and normal plane of spatial curve and surface, economic application of derivative, economic application of definite integral, simple abnormal double integral in unbounded region, Bernoulli equation and total differential equation in ordinary differential equations, some differential equations that can be solved by substitution of simple variables, Euler equation and so on.

2, the second math exam content are:

Curvature and curvature circle in derivative application, physical application of derivative, integral of rational function in definite integral, rational integral of trigonometric function, integral of simple irrational function, lateral area of rotating body and arc length of curve, as parallel cross-sectional area of known solid volume, physical application of definite integral (work, gravity, pressure, center of mass, center of mass, etc. ), reduced-order differential equations, some homogeneous linear equations with constant coefficients higher than the second order, and differential equations.

What I didn't mention was the same math 123 * * exam, so I won't go into details.
