The rainfall $R(t)$ (in $\text{ mm}$) over the course of a year in Bali, Indonesia as a function of time $t$ (in days) can be modeled by a sinusoidal expression of the form $a\cdot\sin(b\cdot t)+d$. At $t=0$, in mid-April, the expected daily rainfall is $2.3\text{ mm}$, which is the average value throughout the year. One-quarter of the year later, at $t=91.25$, the rainfall is at its minimum, at an expected daily value of $1.4\text{ mm}$. **Find $R(t)$.** *$\textit{t}$ should be in radians.* $R(t) = $ [[☃ expression 1]]
