fresnelIntegralC¶

Evaluates the cosine Fresnel integral.

Synopsis¶

fresnelIntegralC (x)

Required Arguments¶

float x (Input): Argument for which the function value is desired.

Return Value¶

The cosine Fresnel integral.

Description¶

The cosine Fresnel integral is defined to be

$C(x) = \int_0^x \cos \left(\tfrac{\pi}{2} t^2\right) dt$

Example¶

The Fresnel integral C(1.75) is evaluated.

from __future__ import print_function
from numpy import *
from pyimsl.math.fresnelIntegralC import fresnelIntegralC

x = 1.75

ans = fresnelIntegralC(x)
print("C(1.75) = %f" % (ans))

Output¶

C(1.75) = 0.321935
