Calculate the angle 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 = `1.745xx10^(-2)` rad
(b) `1^(@) = 60. = 1.745xx10^(-2)` rad
`1.=2.908xx10^(-4)` rad `~= 2.91xx10^(-4)` rad
`("c") 1.=60" = 2.908xx10^(-4)` rad
`1" = 4.847xx10^(-4)` rad `~= 4.85xx10^(-6)` rad
