Q15 (c)

A sound wave can be modelled using a function P(t)=ksin⁡(at)P(t)=k\sin(at)P(t)=ksin(at), where PPP is air pressure in Pascals, ttt is time in milliseconds (ms), and kkk and aaa are constants.

Hence, find the values of ttt, where 0<t<100<t<100<t<10, for which functions P1(t)P_1(t)P1​(t) and are BOTH decreasing.
