THE publication of these tables helps to mark a change in the use of logarithms, both for teaching and practical purposes. Nowadays most teachers use four-figure tables for teaching purposes, even in ...

Astronomers prepared tables of trigonometric functions (especially for triangles on a sphere) from ancient times. With the introduction of the printing press, and the rapid decrease in the cost of ...

PERHAPS the best way of treating this work, which does not contain a single word of explanation, will be to give a summary of the tables contained in it. First we have proportional parts of all ...

Trigonometry is the branch of mathematics that explains the relationship between sides and angles of a triangle. In a right angled triangle the three sides are perpendicular, base and hypotenuse, as ...

You’re standing at the edge of a cliff, phone in hand, trying to measure the distance to the opposite side – no tape measure, no drone, just your brain. Now what? Trigonometry just became your ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Working with trigonometric relationships in degrees Trigonometric functions can ...

In one of your math classes, you might have been taught that geometry and trigonometry were products of the ancient Greeks. That's not entirely accurate, as a new discovery proves that both were ...

Thankfully, very few of us have to bother with trigonometry on a daily basis, but regardless of how much you may have dreaded studying it (or any math, for that matter) in school, it's still ...
