Quick Aside: How the Columns WorkThe "mini triangle" strategy works for all the trig functions. There are 3 factors:Q1: What's the sign?The trig co-functions are the original function applied to the complementary angle.Just eyeballing it, we see parameters x and (90−x) bandied about....
One aspect where we need to employ a trigonometry triangle calculator is in the designing of buildings and roads. You may have seen surveyors working on-site to find out the angle of the sun, the wind and the gradient in order to reach the best parameters for a building design and ...
For instance, find the sine and cosine of 10o, then of -10o. Are the two cosines the same? Are the two sines opposite? One more example of the usefulness of the unit circle: textbooks often give you an angle, and ask you if the sine and cosine are negative or positive. They ...
