Answer:
B
Step-by-step explanation:
Euler's formula tells you that ...
cos(θ) +sin(θ)·i ≡ e^(i·θ)
__
So, for θ = 90° (= π/2 radians), this is ...
cos(π/2) +sin(π/2)·i = 0 +i = i = e^(i·π/2) . . . . . matches choice B
For 6, 30. For 7, 20. And for 8, 15.
0.5cm^3
volume of rectangular prism= length x width x height
1/4cm x 1/2cm x 4cm =
0.25cm x 0.5cm x 4cm =
GOOD LUCK TO HIM AND YOU!! YOU GOT THIS!!! Be sure to have fun though.
