In general, identifying the reference angle for an angle will help So for the fifth root, get the fifth root of 243, then divide 240 by 5 for your first angle. To find this answer on the unit circle, we start by finding the sin and cos values as the y-coordinate and x-coordinate, respectively: sin 30° = 1/2 and cos 30° = √3/2. We should learn it like. Now use the formula. r = 3 and 5Ф = 240 +360p so Ф = 48 + 72p. Method 2. It is, basically, what happens in your pocket calculator when you evaluate, for example, #sin (30°)#. bölgede sin açısının işareti eksi olduğundan dolayı işlemin önüne ( - ) işareti getirdik.
