Rewriting the left hand side,
csc²t - cost sec t
= (1/sin²t)-(cost)(1/cost)
= 1/sin²t - 1
= 1/sin²t - sin²t/sin²t
= (1-sin²t)/sin²t
= cos²t/sin²t
= cot²t
Answer: Midpoint= -13/2, -4
Step-by-step explanation:
Midpoint formula is (X1+X2)/2, (Y1+Y2)/2
So.
1. (-7+(-6))/2, (-7+(-1))/2
2. That equals -13/2,-4
First you combine the like terms which are the Ws.
And if there's no number in front of the variable (w in this case) it
