1. thomas paine, a key figure in the american revolution, once said, "it is only
error, and not truth, that shrinks from inquiry." what do you think he meant by
this?
2. do you think any significant discoveries have been made from errors? can you
describe one?
3. when doing an investigation, if you were to make a mistake what do you

27. =3,500,000 x 4,000 = 14,000,000,000

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
