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.
Euler angles represent a sequence of three elemental rotations, i.e. rotations about the axes of a coordinate system. For instance, a first rotation about z by an angle Î±, a second rotation about x by an angle Î², and a last rotation again about z, by an angle Î³. These rotations start from a known standard orientation.
