sec-1 This can be a reference to speed, though it is most commonly a reference to frequency. sec-1, or 1/sec can also be referred to as the Hertz (Hz), or cycle per second.
1 min = 60 sec Hence 1 sec = 1/60 min
45 sec / 1 hr = 45 sec / 3600 sec = 1/80
For any calculator Sec(Secant) = 1/Cos Csc (Cosecant) = 1/ Sin Cot (Cotangent) = 1/Tan
sec
10 sec/1 min = 10 sec/60 sec = 1/6
4 sec/1 min = 4 sec/60 sec = 1/15
1 min. = 60 sec. 60 min. = 1 hr. 1 hr. = 3600 sec. 24 hr. = 1 day 1 day = 86,400 sec. 7 days = 1 week 1 week = 604,800 sec. 13 weeks = 7,862,400 sec.
Ut is equual to tan(theta) / (sec(theta) + 1)
SEC
sec x = 1/cos x so sec x * cos x = 1
sec(x)=1/cos(x) - (hint: look at the third letter: sec->(1/)cos, cosec->(1/)sin, cot->(1/)tan)
