Just looking for help on part B thanks!

$(03)$Use Taylor's method of order $4$ to approximate the solutions for each of the following initial value problem.

a$.y^{\text{'}}=y^2-\frac{y}{t},$ for $1t1\mathrm{.}6$ with $y(1)=1$ and $h=0\mathrm{.}1$

b$.y^{\text{'}}=t+2y,$ for $1t2$ with $y(1)=1$ and $h=0\mathrm{.}2$
