Express the given angles into radian. ...

Express the given angles into radian.
(a) `1^(@)`
(b) `12 sec`.

Text Solution

Verified by Experts

(a) We know, `(2pi) "rad" = 360^(@)`
`1^(@)=((pi)/(180))"rad"`
`implies 1^(@)=1.74xx10^(-2)"rad"`
(b) `1^(@)= 60.= 3600..`
`implies 1..= (1^@)/(3600)`
`implies 12..=12xx((1)/(3600))^(@)`
`implies 12.. = 12xx(1)/(3600)xx1.74xx10^(-2)"rad"`
`cong 5.8xx10^(-5)"rad"`.
