1. The problem statement, all variables and given/known data see attachment please 2. Relevant equations 3. The attempt at a solution y= sin(2t)+t x=e2t ln(x)=2t t=ln(x)/2 y=sin(2(lnx/2) )+ln(x)/2 y=sin(ln(x))+ln(x)/2 the question says leave in terms of t but when i differentiate i get y'=cos(ln(x))/x+1/2x this may not even be what the question is asking??? but if it is how do i put that back in terms of t???
