Tangent without calculator
WebTrigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

WebTrigonometry involves three ratios - sine, cosine and tangent which are abbreviated to \(\sin\), \(\cos\) and \(\tan\). The three ratios can be found by calculating the ratio of two sides of a ... WebOur answer was pi over 4. Let's see if we get that when we use our calculator. So the inverse tangent of minus 1 is equal to that. Let's see if that's the same thing as minus pi over 4. …
WebExplanation: For tan 120 degrees, the angle 120° lies between 90° and 180° (Second Quadrant ). Since tangent function is negative in the second quadrant, thus tan 120° value = -√3 or -1.7320508. . . Since the tangent function is a periodic function, we can represent tan 120° as, tan 120 degrees = tan (120° + n × 180°), n ∈ Z.

WebThere's an angle in QII, namely 135 degrees, whose tangent is -1, and there's an angle in QIV, namely 315 degrees (or -45 degrees, if you prefer) whose tangent is -1. In order for arctan to be a function, arctan(-1) must have just one value, and the same has to be true for arctan(x), no matter what real number x stands for.
