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 ...

Last week we published a series of posts debunking Trig Trutherism, the idea that Sarah Palin is not the mother of the young Trig Palin. Andrew Sullivan, who is the most prominent Trig doubter, has ...

Excel has built-in functions for sine and cosine, the two core trigonometric functions, and for hyperbolic sine and hyperbolic cosine, their hyperbolic counterparts. It also has built-in functions for ...

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 ...

Learn how to write the trigonometric equation of a graph step by step by identifying the key features that shape sine and cosine functions. You’ll see how to find the amplitude, period, midline, phase ...

The trigonometric ratios sine, cosine and tangent are used to calculate angles and sides in right angled triangles. We are now going to extend trigonometry beyond right angled triangles and use it to ...

The Babylonian civilization was at its peak roughly 4,000 years ago, with architecturally advanced cities throughout the region known today as Iraq. Babylonians were especially brilliant with math, ...

a missing side in a right-angled triangle when another side and an angle are known. a missing angle in a right-angled triangle when two sides are known. In these formulae, the Greek letter θ (theta) ...
