 · An angle is in "standard position" when the vertex is at the origin and the initial side of the angle is along the positive xaxis A Positive angle measured in counter clockwise direction from the Horizontal (xaxis) Thus, the initial side of the angle 3π 4 is coincides with Positive side2 π radians = 360 ∘ π radians = 360 ∘ 2 = 180 ∘ 1 radian = 180 ∘ π ≈ 573 ∘ 2 π radians = 360 ∘ π radians = 360 ∘ 2 = 180 ∘ 1 radian = 180 ∘ π ≈ 573 ∘ Note that when an angle is described without a specific unit, it refers to radian measureDetermine the coterminal angle of π/4 Solution Given Angle θ = π/4, Which is in radians, So, multiples of 2π add or subtract from it to compute its coterminal angles Now, subtract 2π from the angle = π/4 − 2π = −7π/4 Hence, the coterminal angle of π/4 is equal to −7π/4 Example 2

Radian Measure Including How To Convert Radians To Degrees And The Trigonometric Functions Of Special Angles

An angle in standard position whose terminal side intercepts an arc of length r Because the circumference of a circle is 2πr, there are 2π radians in a full circle So, degree measure and radian measure are related by the equation 360° = 2π radians, or 180° = π radians STUDY TIP If two angles differ by a multiple of 360°, then theSo, by the example above and the fact that a circle is 360o, we see that 2π radians = 360o or π radians = 180o To convert from degrees to radians, multiply degrees by π rad o/ 180 (πA = n / 2 sin τ / n A = n / 2
