Explaining radians
WebTo convert 15.6358 degrees to deg min sec form do: Clearly we have 15 degrees, so the remaining 0.6358 is minutes and seconds. Since one degree has 60 min, we can write that x = 0.6358 * 60 So x is 38.148 min. A simpler example would be 0.5 degrees is equivalent to 0.5 * 60 = 30 minutes, so half of one degree, which makes sense. WebThe unit circle represents a complete angle of 2π radians. And the unit circle is divided into four quadrants at angles of π/2, π. 3π/2, and 2π respectively. Further within the first quadrant at the angles of 0, π/6, π/4, …
