Answer:
√2
Step-by-step explanation:
tan(x) = -1
x = arctan(-1)
x = -π/4
Now since x is between 3π/2 and 2π use use the general form
nπ-π/4
taking n = 2
2×π-π/4
= 7π/4
now tan (7π/4) = -1
so sec (7π/4) = √2

Answer:
= 28/45 (Decimal: 0.622222)
Step-by-step explanation:
Simplify:
(1−1/4)(1−1/9)(1−1/16)(1−1/225)
=((1−1/4)(1−1/9)(1−1/16))(1+−1/225)
=((1− 1/4 )(1− 1 /9 )(1− 1 /16 ))(1)+((1− 1 /4 )(1− 1 /9 )(1− 1/ 16 ))( −1 /225 )
=5/8 + −1/360
= 28/45 (Decimal: 0.622222)
