Create an app in MATLAB App Designer. Use a RadioButton Group to choose the different functions. When you choose one function it should be displayed in a graph in the app and the title should state which graph it is. the functions are sine,cosine,lnx

Steps: (Or Refer any tutorial, please check in the MATLAB youtube channel)

1. Open MATLAB

2. Type the following in the command window

    >> appdesigner   

2. Just drag and drop all required blocks, chahe the texts as per requirements

4. Call Back activate (Right Click on the Radio Button Group)

5. Insert the following code, its just the if else condition

6. Run the code

            SteselectedButton = app.yButtonGroup.SelectedObject;
            x=1:0.05:100;
            if app.sinxButton.Value  
            y=sin(x);
            plot(app.UIAxes,x,y);
            title(app.UIAxes,'y=sin(x)');
            elseif app.cosxButton.Value
            y=cos(x);
            plot(app.UIAxes,x,y);
            title(app.UIAxes,'y=cos(x)'); 
            elseif app.xButton.Value
            y=2*x;
            plot(app.UIAxes,x,y);
            title(app.UIAxes,'y=2x');  
            elseif app.lnxButton.Value
            y=log(x);
            plot(app.UIAxes,x,y);
            title(app.UIAxes,'y=ln(x)');
            else
            y=exp(x);
            plot(app.UIAxes,x,y);
            title(app.UIAxes,'y=e^x');   
            end
