Hi, below I have a code to solve symbolically differential equation.
My question is simple:
How to present the solution in linear form instead of exponential form. So basically what is the code to logarithm symbolically function on both sides of the solved equation?
syms A(t) k A0
R = -diff(A) == k*A;
cond = A(0) == A0;
A(t) = dsolve(R,cond)

请先登录，再回答此问题。

Use 'simplify' function on applying log on both sides of equation
z= log(A(t));
logA = simplify(z , 'IgnoreAnalyticConstraints', true);
