find an angle which is coterminal to 15pie/4
subtract by 2 pie
a=15pie/4-2pie
resulting angle of 7pie/4 is positive ,less than 2pie and coterminal with 15pie/4
a=7pie/4
sec(7pie/4)= hypotenuse/adjacent
subsituting the value into the defination
sec(7pie/4)=1/underoot 2/2
multiply the numerator by the reciprocal of the denominato
1( 2/underoot2)
multiply 2/underoot2 by 1 to get 2underoot
multiply 2/underoot2 by underoot2/underoot3
2/underoot2 underoot2/underoot2
ans is underoot 2
