Before I put out my answer, I just want make note that sec() = 1 / cos() and csc () = 1 / sin ()
1) Once you distribute cos()sin() to sec(), the cos() will cancel out with the sec() to make it just sin(), and once cos()sin() is distributed to csc(), the sin() will cancel out with the cos()
2) After doing that you should just be left with sin() + cos()
3) And since no more simplification can be done, that is your answer :D

Let
, so that differentiating both sides wrt
gives

If
and
, the above reduces to

This is the slope of the tangent line, which has equation

Answer: Supplementary Angles
Step-by-step explanation:
Supplementary angles are a pair of angles whose sum is 180°. 45° and 135° add up to 180°. Therefore, the answer is supplementary angles.
Vertical line are represented by x = a number....that number being the x value in ur set of points
so ur equation is : x = -7
