Question
Solve the following initial value problem:
Cos(t)? dy
= 1
dt
Transcribed Image Text:Solve the following initial value problem: Cos(t)? dy = 1 dt
with y(21) = tan(21).
(Find y as a function of t.)
y = tant
B. On what interval is the solution valid?
(Your answer should involve pi.)
Answer: It is valid for 13pi/2
<t< 15pi/2
C. Find the limit of the solution as t approaches the left end of the interval. (Your answer should be a number or "PINF" or "MINF".
"PINF" stands for plus infinity and "MINF" stands for minus infinity.)
Answer: 0
D. Similar to C, but for the right end.
