Webat 180 degres, or pi radians we are at the x axis again, but on the negative side. again, y is 0 but x is negative rather than an angle of 0. third quadrant is the quadrant on the negative x axis side and negative y axis side, so both x and y are negative here. 270 degrees/ 3pi/2 radians is the negative y axis, so x is 0 and y is negative. WebWell, the textbook answer is that there are only 6 trig ratios, which we have already covered. However, if you really want to devel into the topic, the historical answer would be that there are at least 12 ratios, which include the ones we've learned and some new ones which are versine, haversine, coversine, hacoversine, exsecant, and excosecant.

In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides. For example, if one of the other sides has a length of 3 (when squared, 9) an… WebJun 8, 2024 · Because it is the length of the side of a triangle and the length of a real object cannot be negative.
