lim t → 0

e^9t i + (Sin(4t))/(4t) j + e^(-5t) k

My approach was to plug in 0 and get i+k but that didn't go through with webassign. So I tried the DNE answer because maybe since the y could be undefined, the whole thing is, but that was wrong. So lastely I punched it into my calculator, got the decimal answer and that didn't work for i + (decimal) j + k.

Does anyone know how to solve for the limit?
