Find the rms value of the function i=15(1e to the power of 1/2 t) from t=0 and t=4?
A.7.5 sqrt 1+4e^2 e^4 <<<<my answer?
B.7.5 sqrt 42e^2 + e^4
C.7.5 sqrt 4+4e^2  e^4
D.7.5 sqrt 52e^2 + e^4

For the first part, A is correct.
(see my response at

For the second part, A is also correct.
7.5sqrt(1+4e^(2)e^(4)) 
thank you so much MathMate .
