Apparently there are definite integrals , Which are sure of their status, But there are also indefinite and improper integrals. My math teacher tried to introduce me to higher order numbers. This we call geometry . Geometry includes the study of lines. Some are normal lines, Some like to go off on tangents , And some form envelops .
Geometry also involves angles.
Some angles are really acute , while others are obtuse . When dealing with angles, finding the answer is called a coincidence . It is almost impossible to differentiate between A right angle, and a wrong angle. Numbers can be inconsistant . When you can't make up your mind, use indefinite form.
