The answer is 59,280 . To find you multiply 40 x 39 x 30 which 59,280
No 2 times 4 is 8 and 3 times 3 is 9, 8 plus 9 is not 33 it’s 17
Frequency
= (pi)/(2pi)
= 1/2
Answer:
x = π/6, π/2, 5π/6, 3π/2
Step-by-step explanation:
cos x = sin(2x)
Use double angle formula.
cos x = 2 sin x cos x
Move everything to one side and factor.
cos x − 2 sin x cos x = 0
cos x (1 − 2 sin x) = 0
Set each factor to 0 and solve.
cos x = 0
x = π/2, 3π/2
1 − 2 sin x = 0
sin x = 1/2
x = π/6, 5π/6
The total solution is:
x = π/6, π/2, 5π/6, 3π/2
