Answer:
sec(330°)cos(330°) = 1
Step-by-step explanation:
given data
theta = 330
to find out
sec(theta°)cos(theta°)
solution
we have given equation
sec(theta°)cos(theta°) ......................1
so put here value of theta in equation 1
= sec(330°)cos(330°) ..............2
we know sec(330°) = [tex]\frac{1}{cos330}[/tex]
so from equation 2
= [tex]\frac{1}{cos330}[/tex] cos(330°)
= 1
so here sec(330°)cos(330°) = 1
