So we have the two equations:
To make a substitution of the second equation into the first equation, we need to isolate the <em>y </em>variable in the second equation. Thus:
Now, we can substitute this into the first equation. Therefore:
Write tan in terms of sin and cos.
Recall that
Rewrite and expand the given limand as the product
Then using the known limit above, it follows that
Answer: The system consists of parallel lines
Step-by-step explanation:
Given system of lines :
Substitute in
, we get
, which is not true.
That means , system has no solution.
i.e. they are representing parallel lines. [Parallel lines do not intersect and hence they do not have solution.]
