Answer:
cot . (x- π/2)= - tanx
Step-by-step explanation:
cot . (x- π/2)= - tanx
cot .x - cot π/2= - tanx
cot π/2= 1/tanπ/2
But tan π/2= ∞
cot π/2 = 1/∞= 0
cotx - 0= - tanx
cot x = - tanx
cosx/sinx= - sinx/cosx Putting values of cot and tan
cosx/ sinx ( sinx/cos x) = -sinx/cos x (sinx/cos x )
Multiplying both sides with sinx/cos x
1= - sin²x/cos²x
cos²x= - sin²x as cosx = -sinx
Answer:
2.5mph (miles per hour)
Step-by-step explanation:
Simple, 12.5/5 = 2.5 mph (miles per hour)
For function
we have that
. This means that period of cosine function is π. Then from the formula for period
you obtain that
and b=2.
So, the function is
. If f(0)=4, then
and, respectively, a=4.
Answer: 
.
Answer:
Area= 50.24 inches square
Step-by-step explanation:
Area of a circle = π r² diameter= 2*radius
Area= 3.14*(16) ²
Area= 50.24 inches square
