Frequently issued with the treatises on surveying of John Gummere, Robert Gibson, and Zachariah Jess. Authorship has been ascribed to Gummere, Gibson, and also to John Robertson. "Stereotyped by J.

THE book by Mr. M'Aulay is of a very handy size, specially adapted for the pocket. The author, in the preliminary pages, explains the general properties of logarithms and the use of the tables which ...

The mathematical study of triangles has just got a whole lot simpler, according to a researcher who says his new theory of trigonometry is easier to use and more accurate. Associate Professor Norman ...

Calculate the length AB. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). The length \(h\) is ...

Calculate the angle QPR. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). In the triangle the ...

Trigonometric identities are powerful tools for simplifying complex equations in math and science. Three core groups—reciprocal, quotient, and Pythagorean—form the foundation. Effective strategies ...
