Calculate the angular of (a) `1^(@)` (degree) (b) 1' (minute of arc or arcmin) and (c) 1'' (second of arc or arc second) in radians. Use `360^(@)=2pi` rad, `1^(@)=60'` and `1'=60''`

Text Solution

Verified by Experts

(a) We have `360^(@)= 2pi` rad
`1^(@) = (pi//180) "rad" = 1.745 xx 10^(-2)` rad
(b) `1^(@) = 60. = 1.745 xx 10^(-2)` rad
`1.= 2.908 xx 10^(-4) " rad" = 2.91 xx 10^(-4)` rad
(c ) 1. = 60. `= 2.908 xx 10^(-4)` rad
`1..= 4.847 xx 10^(-6) " rad" = 4.85 xx 10^(-6)` rad
