convert to radian

sec(1.24) to radian

 

Sec=1/Cosine(1.24)=1/.999766=(1.000234 x Pi)/180 radians

 

Sec=.01745738 radians.

sec(1.24) to radian

 

The question does not really makes sense

sec(1.24) is a ratio not an angle so how can you express it in radians?

 

You probably mean that 1.24 is an angle in radians

 

Set your calc to radians and then just enter it

 

1/cos(1.24) = 3.0788
