-54 i think is the answer
Answer:
(a) θ = π + 4πn
(b) θ = π
Step-by-step explanation:
(a) sin(θ/2) − 1 = 0
sin(θ/2) = 1
θ/2 = π/2 + 2πn
θ = π + 4πn
(b) Try different values of n.
n = -1, θ = -3π
n = 0, θ = π
n = 1, θ = 5π
If 0 < θ < 2π, then θ = π.
To evaluate this expression properly, we must follow order of operations (PEMDAS) rules. Here, that means doing exponentiation first, followed by mult. and div., followed by addition and subtraction.
2−4÷2+2^3 becomes 2−4÷2+8 after exponentiation.
2−4÷2+8 becomes 2-2+8 after division.
2-2+8 = 8
Your final value for this expression is 8.
