your expression for will have an arbitrary constant . you can find this by plugging in and setting the expression to 1, since .

similar to the last problem, you have to do the above twice.2. Find s(t). s''(t) = -1, s'(0) = 3, s(0) = 7.

first find and find the arbitrary constant, then find and find the arbitrary constant

by the fundamental theorem of calculus, if is the anit-derivative of , then3. The integral with lower limit 1 and upper limit e, (3/x)dx

Could someone help me get these started? Thanks!

i suppose you can find
