Maple syntax for solving for t:

solve(14.2857*exp(-t)-0.0045exp(-1.0175*t)-14.2857*exp(-(t-5))-0.0045exp(-1.0175*(t-5))+7.368=0, t);

Note: Equation was obtained from chemical engineering process control problem. This is the case for t > 5. For t < 5, we have:

solve(-0.2457+14.2857*exp(-t)-0.0045exp(-1.0175*t)+7.368=0, t);

I have tried multiple times for both cases, but Maple still runs forever. How can I solve this issue?

I want to use Maple (dsolve command) to solve this problem, how do I input the command? Part (a) is enought.

I have tried the command, but Maple says "Warning, for {u(t)} arbitrary the system is inconsistent".

Thank you very much for your help.

Can someone help me whith this plot? Somehow Maple always says unable to evaluate the function to numeric values in the region.

File is attached.

I am currently doing a project for mass transfer class. Here is a differential equation that I need to solve:

For the solution, and plug in the value of C_AS and C_A0, I finally got the concentration profile of:

Then I write the commands and Maple won't give me a plot (no warnings appeared). Can someone help me with this situation?

I am currently studing mass transfer (chemical engineering major), there is an equation that we need to plot to solve the problem. The equation is attached below.

When I use maple to plot this equation, it always come up "Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct". Does anyone know how to plot this equation? Thank you very much for your help.
