The area under the normal curve
from properties of normal curve said The area under the normal curve over the axis, all the areas under the curves = 1
Of any variable, such as the area under the curve between 1 with 2 is shaded areas, as shown in the picture 1.5
the 1.5
calculation of area under the curve Can do all the value of the value of, which can
Calculate the area of the integrator. Using grade in calculus, that is, the area under the curve of 1 to 2 is
Calculation of area under the normal curve of the formula is rather difficult Therefore, the invention to schedule calculated according to the formula. At various values, but because the curve normally have several lines, depending on the value ofThus the idea of conversion, such as the value
