Step-by-step explanation:
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
Answer:
-6: integer, rational, real
0: whole, integer, rational, real
0.222...: rational, real
15/3: whole , integer (if talking 5), rational, real
2: all except irrational
√3: irrational, real
-12/6: Integer, rational, real
Answer:
1,572,861
Step-by-step explanation:
1. 3
2. 6
3. 12
4. 24
5. 48
6. 96
7. 192
8. 384
9. 768
10. 1536
11. 3072
12. 6144
13. 12288
14. 24576
15. 49152
16. 98304
17. 196608
18. 393216
19. 786432
Now we have to add all those
786432 + 393216 + 196608 + 98304 + 49152+ 24576 + 12288 + 6144 + 3072 + 1536 + 768 + 384 + 192 + 96 + 48 + 24 + 12 + 6 + 3..
This is alot of math but it equals 1572861
1,572,861
