Can t^(-1) be written as 1/t

the question is like y_2(t)=t^(-1) but in the steps they have put the problem like y_2(t)=1/t so i was wondering is that fine?? thanks-Yes.t^(-n) = 1/(t^n) in general and in this case t^(-1 = 1/(t^1

How do I do this Sequences limit question

How do I evaltuate this limit as n goes to infinity? (n^n)/((n+3)^(n+1)) Please show your working Thanks, James-What if we factor the denominator (n + 3)^(n + 1) as (n + 3)(n + 3)^n ? Then, our ra

How do you find the derivative of tan^2(x^3)

f(x) = tan²(x^3) f(x) = [tan(x^3)]² Use the power rule and chain rule: f (x) = 2tan(x^3) * d/dx[tan(x^3)] Use the chain rule and the fact that d/dx[tan(x)] = sec²(x): 2tan(x^3) * sec²(x^3) * d/dx[x^3]
