I know we can use the subsittion of m = y' for 1 and 2, then let y'=m(y(t))for 3 and 4, but I have a hard time to solve for the answer
as the answers are given, can anyone show me the setps, I need to undertsand this for the test tomorrow
the question is inside the image and
tha answers are
1. $\displaystyle C1x^2+C2$
2. $\displaystyle C1lnt+C2+t^2$
3. $\displaystyle [C1+C2^{e^t}]^{1/2}$
4.$\displaystyle C1 tan(C1t+C2)$
