Answer :
The answer will be t=-35Sin{[tex]\pi[/tex]/6m)+55 average daily temperature, t, in degrees Fahrenheit for a city as a function of the month of the year.
What is temperature?
Temperature is the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
For the equation: 35cos(pi/6(m+3)+55)
Simplify it by multiplying pi/6 in the bracket values:
[tex]=35 Cos (\dfrac{\pi m}{6}+\dfrac{3\pi }{6}+55)[/tex]
[tex]=35 Cos(\dfrac{\pi m}{6}+55+\dfrac{\pi}{2})[/tex]
Now suppose x = m.pi/6+55, while pi/2 = 90⁰
As per law cos(x+90⁰)=-sin(x)
so,cos((m.pi/6)+55+90⁰=-sin((m.pi/6)+55)
Hence answer will be
[tex]=-35Sin(\dfrac{\pi m}{6}+55)[/tex]
The law cos(x+90⁰)=-sin(x) can be proved by putting y=90⁰ in the following formula,
cos(x+y)=cos(x).cos(y)-sin(x).sin(y)
Hence the answer will be t=-35Sin{[tex]\pi[/tex]/6m)+55 average daily temperature, t, in degrees Fahrenheit for a city as a function of the month of the year.
