1, mathematical formula: parabolic standard equation y 2 = 2pxy2 =-2pxy2 = 2pxy2 =-2py. Lateral area of a right-angled prism s = c * h. lateral area of an oblique prism s = c * h. lateral area of a regular pyramid s =1/2c * h. lateral area of a prism s =1/2 (c+c) h. lateral area of a frustum of a cone s =1/2 (c

2. The side area of the cylinder is s = c * h = 2π * h The lateral area of the cone is s =1/2 * c * l = π * r * l. The arc length formula l=a*r a is the radian number r >； of the central angle; 0。 Sector area formula s =1/2 * l * R. cone volume formula v =1/3 * s * h. cone volume formula V= 1/3*pi*r2h. Oblique prism volume V=SL Note: where S is the straight cross-sectional area, L is the side length, and the cylindrical volume V = S * H is the formula.

Basic properties of logarithmic function:

1 crosses the fixed point (1, 0), that is, when x= 1, y=0.

2. When 0

3. Logarithmic function is a parity function (whether increasing function or subtraction function), and its anti-exponential function is also a parity function.
