Build the graph according the table of values using cubic spline (task for all variants is the same; N is number of variant).

To do this task we should build table of values, than build two graphs in 1 coordinate system and on1 graph determine points as box.

As there was shown on the example here we should apply the trace-box.

17.

To do this task we should write 2 equations of graph and build them with a help of the 3D Plot Wizard. Than determine point of maximum.

. Find the maximum or minimum value of the function in consideration of conditions.

To find these values we should solve the equation and build 3D surface with help of 3D of Plot Wizard in graph Toolbar.

18. The probability distribution of casual value x is given in the table. Calculate the probability of existing x within interval [a, b]. Draw the graph, copy it in the report as a vector graphics and fill by red color the square corresponding probability that has been found.

For building the normal probability of this function we should build in 1 coordinate system 2 graphs and determine the step of the function, but with very small value and limits that we need.

In this task firstly we entered the equation according to the variant.Then we entered x:=(0,0.01:25) to have painted figure.Then when I built this graph I used trace 2 none and grid lines in unit Advanced.An got graph as on the example.

19.

Build the function that models the signal from the table. Calculate the Fourier spectrum of the signal. Build the approximation of the signal using 4 non-zero harmonics.

. To build this graph we should use the table of values and build this in Cartesian coordinate system.

In this task I used also grid lines crossed in advanced unit.

Conclusion: working in this program I learned how to built the graphs of the different problems and using different functions to solve them by different ways.
