If period of

is one-half the period of

and
<span>

has a period of 2π, then

and

.
</span>
To find the period of sine function

we use the rule

.
<span /><span />
f is sine function where f (0)=0, then c=0; with period

, then

, because

.
To find a we consider the condition

, from where

.
If the amplitude of

is twice the amplitude of

, then

has a product factor twice smaller than

and while period of

<span> </span> is 2π and g(0)=0, we can write

.

Answer:
× π10 = 7
Explanation:
The formula to find arc length is
× 
Simply plug in radius and arc length to get your equation.
Answer:
h(7) = 29
h'(7) = 44
Step-by-step explanation:
If
, to find h(7) we can substitute the values of f(7) and g(7) and we get:

To find the derivative, we know that the derivative of a sum of functions equals the sum of the derivatives of those functions.
This would mean that
, we can substitute the values for f'(7) and g'(7)
