Answer:

Step-by-step explanation:

For positive rate of change 

<h3>
Equation Step by Step</h3>
sin(4(3.141593^3)+3.141593^4)
sin((4)(31.006277)+3.141593^4)
sin(124.025107+3.1415934)
in(124.025107+97.409091)
sin(221.434198)
=0.998844
Tbh, might be wrong on this one. I'm on the road so didn't double-check my answer.
