Solve the following initial value problem: cos(ð¡)2ðyðð¡=1 with y(12)=tan(12). (find y as a function of ð¡.) y= . b. on what interval is the solution valid? (your answer should involve pi.) it is valid for < ð¡< . c. find the limit of the solution as ð¡ 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.)
