The rate of intake, R, during respiratory cycle for a person at rest is proportional to a sine wave with period 6 seconds. If the rate of intake is 0.89 liters per second at 1.5 seconds, find the formula for R

Question

anonymous · Answer

since time period is given as 6, we can calculate it's $$R(t)= 0.89 \sin( \frac{ \pi }{ 3 } * 1.5)$$

is that the final answer?

anonymous · Answer

yep!!! it is.. you can solve further for values inside sin..but overall it's the equation.
you know he equation will be of the form: 
r = c*sin(kt)
right??

anonymous · Answer

yeah that makes sense

anonymous · Answer

awesome!! u just need to substitute the values ...
since we know the period is six seconds, k must equal 2Pi/6 ...finally u will get the above R(t) @mnrydman
