1 I think. Tell me if that is correct
All the equivalent fractions.
I'm fairly certain that's correct but check again if you need to and please, correct me if I got something wrong.
For this case we have the following fraction:
(1-cos ^ 2 (θ)) / (sin ^ 2 (θ))
We must take into account the following trigonometric identity:
cos ^ 2 (θ) + sin ^ 2 (θ) = 1
Therefore rewriting we have:
sin ^ 2 (θ) = 1 - cos ^ 2 (θ)
Substituting in the given fraction we have:
(1-cos ^ 2 (θ)) / (sin ^ 2 (θ))
= (sin ^ 2 (θ)) / (sin ^ 2 (θ))
= 1
Answer:
1
Answer:
22x - 14
Step-by-step explanation:
pretty sure its like this..
3(4x-3)+5(2x-1)
= 3×4x + 3×(-3) + 5×2x + 5×(-1)
= 12x + (-9) + 10x + (-5)
and according to the rules of multiplying negative by positive...
= 12x - 9 + 10x - 5
combine like terms using the symbols on its left
= 12x + 10x - 9 - 5
= 22x - 14
