I have a problem with solving a simple integration through MATLAB. I want to solve this symbolic and don't have any problems doing this through other programs.
Well I have this equation:
syms k x
fX(x) = k * e^(-3*x) for 2 <= x <= 6
which I want to integrate from the interval 2 to 6. Then I would solve the equation, so that fX(x) = 1, and solve the equation for k. I type:
S = solve('int(k*exp(-3*x),x,2,6) = 1',k);
And I get following error: Error, (in int) wrong number (or type) of arguments: invalid options or option values passed to indefinite integration. Unknown options: {2, 6}
Why can't the int-function not take my limits?
