Four batches should be the correct answer
Answer:
x = 0, π/4, π, 7π/4
Step-by-step explanation:
sin(2x) = √2 sin x
Use double angle formula.
2 sin x cos x = √2 sin x
Move everything to one side.
2 sin x cos x − √2 sin x = 0
Factor.
sin x (2 cos x − √2) = 0
Solve.
sin x = 0, cos x = ½√2
x = 0, π/4, π, 7π/4
Answer:
Perform Multiplication
9+−6−6
Simplify
‐3
Step-by-step explanation:
First multiply -3 by -3 which equals 9. Then multiply 2 by -3 which equals -6. then put it together to get 9+-6-6. Finally do 9+-6=3-6=-3.
As a decimal it is equivalent to 0.5
As a fraction it can be equivalent to 2/4, 3/6, 4/8, 5/10 and so on. Hope this helps :)
