I don’t understand how to do this?
It says find the value of “s” in the interval [0, pi/2] that makes the following statement true:
sec “s” = 4.1924229
I know the value should be between 0-90 degrees, but how do I solve this?

sec x is reciprocaal of 1/cos x
when sec s = 4.1924229
1/cos s = 4.1924229
cos s =1/4.1924229
s= cos^ -1 (1/4.1924229)
from calculator s= 76.2
since the range given in pi change 76.2 to radius
76.2 x (pi/180) = 0.423 pi
range is from 0- 0.5 pi
thus 0.423pi is still in the range
ans: 0.423 pi
n you are right the value is between 0-90 degree
that is 76.2
glad to help..
