1+cos theta+sin theta/1-cos theta+sin theta=cot theta/2​

Step-by-step explanation:

Giventhat,

cosθ+sinθ−1/

cosθ−sinθ+1

=cosecθ+cotθ

Now,

Divide both N and Dr with sinθ

= cosθ−sinθ+1/sinθ / cosθ+sinθ-1/sinθ

= cotθ-1+cos ecθ / cotθ+1-cos ecθ

= cotθ + cos ecθ - ( cos ec²θ - cot ec²θ ) / cotθ - cos ec θ +1

= cotθ + cos ecθ ( 1 - ( cos ec²θ - cot²θ ) / cosθ - cos ecθ + 1

Hope it helps you

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
