WebAD2 = 3a2. Therefore, AD=a√3. Now in Triangle ADB, tan 60 = AD/BD = a√3/a = √3. Therefore, the exact value of tan 60 degrees is √3. We can also derive the values of Tan 0°, 30°, 45°, 90°, 180°, 270° and 360° in the same way. The values of the imporTant Functions of Sin can also be determined by the given method: WebThe bottom triangle is a right triangle with hypotenuse length h = cos phi. So if x were your unknown side, doing normal trig on it gives cos theta = x/h = x / (cos phi), or in other words x = (cos theta)(cos phi). All of the sides in that diagram are defined in the same way, …
