Engineering maths question
I’ve just switched my uni course to engineering and I’m a bit stuck on this maths question. I don’t know if I need an equation to calculate the steady state value or if I just need to sub in some values for t. Genuinely don’t know where to start (for both parts). Could someone point me in the right direction? It’s probably very simple but would appreciate it.

the steady state value would be as t->inf, as stated in the question

Can I just sub in a very big number to get it?

Sort of, but the term which depends on time is a decaying exponential (negative exponent) so you must know what the limiting value is? Note that because of the 15 multiplier, t doesnt have to be that big for the current to be (very) close to the actual limiting value.
