· This arc length provides a new way of representing the measure of an angle, and we call this measure of angles "radian measure" For example, 360 degrees = 2π radians, those are the units;So 90° = π / 2 radians We usually suppress the unit of measurement "radians" since it is understood if no other units for angles is specified Also, since an angle in radians is defined as the ratio of two lengths, L/r, it is dimensionless Since 90° = π / 2 radians, to four significant figures, one radian equals 180°/ π = 5730°1 degree = radians, 1 degree / radians = 1 We can write the conversion as 1 radian = 1 radian * (1 degree / radians) = degrees And we now have our factor for conversion from radians to degrees since 1 * = Note that there are rounding errors in these values Knowing that 1 radian = 57

/07/13 · A degree (arc degree) is defined as 1/360th of the total angle of a circle It is further divided into minutes (arc minutes) and seconds (arc seconds) One arc minute is 1/60th of a degree, and an arc second is 1/60th of an arc minute Another method of subdivision is decimal degree, where one arc degree is divided into 100The Sine function ( sin(x) ) The sine is a trigonometric function of an angle, usually defined for acute angles within a rightangled triangle as the ratio of the length of the opposite side to the longest side of the triangle In the illustration below, sin(α) = a/c and sin(β) = b/cOn the other hand, if the angle measures 36 0 ∘ 360^\circ 3 6 0 ∘ in degrees, then the arc length of the circle carved out by the angle is the circumference of a circle with radius 1 1 1, or 2 π ⋅ 1 = 2 π 2 \pi \cdot 1 = 2\pi 2 π ⋅ 1 = 2 π

Arc length = radius • central angle (radians) arc length = circumference • central angle (degrees) ÷ 360 where circumference = 2 • π • radius Knowing two of these three variables, you can calculate the third Even easier, this calculator can solve it for you Do you want to solve forRadian measure and degrees Since the circumference of a circle is 2πtimes its radius, we have 2πradians =360 =4 right angles, so 1 radian = 360 2π = 180 π = 4 right angles 2π = 2 π right angles or 1 = 2π 360 radians = π 180 radians = 1 90 right angles In high school trigonometry, the trigonometric functions are used to solve problemsIt follows that the magnitude in radians of one complete revolution (360 degrees) is the length of the entire circumference divided by the radius, or 2πr / r, or 2 πThus 2 π radians is equal to 360 degrees, meaning that one radian is equal to 180/ π ≈ 3 876 degrees The relation 2π rad = 360° can be derived using the formula for arc length
