2. • A surface integral is a type of integral that extends the
concept of integration from one dimension (line integrals) to
two dimensions over a surface. It
• involves integrating a function over a given surface to
calculate quantities such as flux, mass, or other physical
properties.
Surfaceintegral.
3. The surface integral
is typically denoted
by the symbol ∮ or ∬
and is defined over a
closed surface S.
The general form of a
surface integral can be
expressed as follows:
∬_S f(x, y, z) dS
4. where:
S represents the surface over
which the integral is
performed.
F(x, y, z) is the integrand, which
is a function of the spatial
variables x, y, and z.
dS represents an infinitesimal
5. The formula for the surface integral of a vector field F over a
surface S is given by:
∫∫S F · dA,
where the integral is taken over the surface S, and dA
represents the differential area vector pointing outward from
the surface.

6. The formula for the
surface integral of a
scalar field f over a
surface S is given by:
∫∫S f dA,
where the integral is
taken over the surface S,
and dA represents the
differential area vector
pointing outward from
the surface
