Answer:
Step-by-step explanation:
We have the following relationships;
We can write;
We note that the numerator of , which is is the derivative of the denominator, , therefore, we can use integration by substitution method and write;
, from which we get;
Therefore, we can write;
Therefore;
csc x + cot x = (1/sin x) + ((cos x)/(sin x)) = (1 + cos x)/(sin x)
(1 + cos x)/(sin x) = (cos²(x/2) + sin²(x/2) + cos²(x/2) - sin²(x/2))/(2sin(x/2)·cos(x/2)) = (2·cos²(x/2))/((2sin(x/2)·cos(x/2)) = cos(x/2)/sin(x/2) = cot(x/2)
Therefore;
Therefore;

Answer:
y = -5x + 5
Step-by-step explanation:
Let the equation of the line be: y = ax + b.
The given points should satisfy the equation.
Substituting the points in the equation we get the values of 'a' and 'b'.
The first point is: (1,0)
⇒ 0 = a(1) + b ⇒ 0 = a + b
⇒ b = -a
(2, -5) is another point. Substituting this we have:
-5 = a(2) + b = 2a - a = a
⇒ a = -5
⇒ b = -a = 5.
Therefore, the equation of the line becomes y = -5x + 5.
