Introduction to trigonometry radian measure:
An angle is determined by rotating a ray about its endpoint. One way to measure angles is in radians. To signify that a given angle is in radians, a superscript c, or the abbreviation rad might be used. If no unit is given on an angle measure, the angle is assumed to be in radians. `(3pi^c)/2-=(3pi)/2 rad.-=(3pi)/2` (Source: Wikipedia)
Trigonometry Radian Measure
Middle angles of a circle contain an angle measure of 1° if it subtends an arc to be 1/360 of the boundary of the circle. These appearances of angle determine is reasonably general. Another appearance of angle determine namely in utilize is radian measure. If a middle angle subtends an arc i.e. identical toward the radius of the circle after that the middle angle contain a computing of one radian.
If a middle angle ? of a circle through radius r subtends an arc of length s, subsequently their radians establish is describing since `theta= s/r`
Given, radius is 4 cm, and length of arc is 60 cm.
We know that the formula for radian measure of `theta=s/r` .
As a result,`theta = 60/4`
?=15
The angle of the arc is 15 radians.
I am planning to write more post on trigonometric function, distance from point to line. Keep checking my blog.
Examples for Trigonometry Radian Measure
Example 1 for trigonometry radian measure
Calculate the angle of the arc, if the radius is 6 cm, and length of arc is 120 cm
Solution:
Given, radius is 6 cm, and length of arc is 120 cm.
We know that the formula for radian measure of `theta=s/r` .
As a result,`theta = 120/6`
?=20
The angle of the arc is 20 radians.
Example 2 for trigonometry radian measure
Calculate the angle of the arc, if the radius is 8 cm, and length of arc is 135 cm
Solution:
Given, radius is 8 cm, and length of arc is 135 cm.
We know that the formula for radian measure of `theta=s/r` .
As a result,`theta = 135/8`
?=17
The angle of the arc is 17 radians.
Example 3 for trigonometry radian measure
Convert 1650 into radians
Solution:
We know that,
`(radians)/pi=(degrees)/180^0`
`radians=degrees pi/(180^0)`
`Given radians = `1650
`radians=165 pi/(180)`
Therefore,`radians=(11pi)/(12)`
