Pie3 years ago

ANSWER:

Let t = logtan[x/2]

⇒dt = 1/ tan[x/2] * sec² x/2 × ½ dx

⇒dt = 1/2 cos² x/2 × cot x/2dx

⇒dt = 1/2 * 1/ cos² x/2 × cosx/2 / sin x/2 dx

⇒dt = 1/2 cosx/2 / sin x/2 dx

⇒dt = 1/sinxdx

⇒dt = cosecxdx

Putting it in the integration we get,

∫cosecx / log tan(x/2)dx

= ∫dt/t

= log∣t∣+c

= log∣logtan x/2∣+c where t = logtan x/2

Answer:

s(x) is t(x) ...

  • horizontally compressed by a factor of 2,
  • reflected across the y-axis, and
  • translated downward 5 units.

Domain and Range

  • t(x) has a domain of x ≤ 0, and a range of y ≥ 0.
  • s(x) has a domain of x ≥ 0, and a range of y ≥ -5.

Step-by-step explanation:

t(x) is the square root function reflected across the y-axis and compressed horizontally by a factor of 2. That is, in f(x) = √x, the x has been replaced by -2x.

s(x) has the function t(x) <em>reflected back across the y-axis</em> and compressed horizontally by another factor of 2. It is also <em>translated downward by 5 units</em>, so that its origin (vertex) is at (0, -5).

_____

The graph shows you the domain and range of s(x). The domain is all numbers to the right of x=0, including x=0. That is ...

  domain: x ≥ 0

The range is all numbers -5 or above:

  range: y ≥ -5

___

For t(x), the argument of the square root function must not be negative, which means the value of x cannot be positive.

  domain: x ≤ 0

For non-negative values of radicand, the t(x) function will have non-negative values. So, the range is ...

  range: y ≥ 0

_____
