Step-by-step explanation:
tan2x = sin2x/cos2x
we know that ,
- sin2x = 2sinxcosx
- sin2x = 2sinxcosx cos2x = cos²x - sin²x
Since, tan2x = 2sinx*cosx/cos²x- sin²x
Dividing by cos²x in numerator and denominator.
We get ,
- tan2x = 2sinx/cosx / 1- sin²x/cos²x
- Since, we get tan2x= 2tanx/1-tan²x
- Option (c) is correct option.
-9+x ?
I don’t know if this is the right answer
The answer is -2. The line is going from left to right which makes it negative. Then if you look at the line and do change in y(rise) over change in x(run).
