Answer:
A. 2·sin(x)·cos(x) - 1 + 2·sin^2(x)
Step-by-step explanation:
The double angle identities can be use directly:
- sin(2x) = 2sin(x)cos(x)
- cos(2x) = 1 - 2sin^2(x)
The difference of these is ...
sin(2x) -cos(2x) = 2sin(x)cos(x) -(1 -2sin^2(x)) = 2sin(x)cos(x) -1 +2sin^2(x)
Answer:
1
Step-by-step explanation:
m=2
3m²- 2m- 7
3(2)² -2(2) -7
3(4)- 4- 7
12- 4- 7= 1
Answer:
A=103.13cm
Step-by-step explanation:
Formula: A= c^2/4π (C being the circumference and ^2 means it's squared)
Plug in what you know: 36^2/4π
1296/4π= 103.13
Answer:
The correct answers are: 0.5, 3, and 10.
Basically, all numbers that are greater than -2.5 can make this inequality true.
