i solved it by using KVL & KCL but my answer is in term of t ! my question is Do they really have values ? i mean ,do i have to find t firstly ? or just write them in term of t only ?

thanks

t is an independent variable and so will appear in your answer. t is measured from any point in real time you choose.
