You will also have a test called a gastric pH level test to measure the amount of acid in your stomach. This helps to tell whether it is a gastrinoma causing the high gastrin levels or if there is another cause. Your doctor may do this test when you are having an endoscopy.
Euler's name is associated with a large number of topics. Euler is the only mathematician to have two numbers named after him: the important Euler's number in calculus, e, approximately equal to 2.71828, and the EulerâMascheroni constant Î³ sometimes referred to as just Euler's constant, approximately equal to 0.57721.
And Paul Nahin, a professor emeritus at the University of New Hampshire, who has written a book dedicated to Euler's formula and its applications in Fourier analysis, describes Euler's identity as being of exquisite beauty. The mathematics writer Constance Reid has opined that Euler's identity is the most famous formula in all mathematics.
