Use matlab to plot the function t=6lnt-7e^(0.2t) over the

interval 1 < t < 3 ( 1
than 3). put a title on the plot and properly label the axes. the

variable t represents temperature in degrees celsius; the variable

t represents time in minutes.

Plot attached.

Explanation:

It is required to plot the function: T = 6 * Ln(t) - 7* e^(0.2*t)

Where t is in minutes ranging from 1 to 3.

T is the temperature in °C.

Matlab uses the expresión: exp() to represent e^()Matlab uses the expression: Log() for Natural logarithm Ln.

The first section of the program: Delete previous calculations and plots. clcclear allclose all

Second section of the program: Declare the time variable and its range.

t = 1:0.1:3;

Third, calculate the Temperature with the function defined previously:

T = 6*log(t) - 7 *(exp(0.2*t));

Finally, we can plot the Temperature vs Time using the plot command, it is required to label the axes with xlabel and ylabel function

plot(t,T)

xlabel('Time [min]')

ylabel('Temperature [°C]')

The plot is attached.
