The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
hope this helps :)
5 - 5b < 1 - 4b
5 < 1 + b
4 < b
1 - 4b < 6 - 5b
1 + b < 6
b < 5
4 < b < 5
(The second less than sign is less than or equal to)
Answer:
Solution given:
- (sinx+cosx)^2-(sinx-cosx)^2
- sin²x+2sinxcosx+cos²x-(sin²x-2sinxcosx+cos²)
- 1+2sinxcosx-1+2sinxcosx
- 2(2sinxcosx)
- 2sin2x
Step-by-step explanation:
[note: sin²x+cos²x=1]
