A variation Use the steps above to create a graph containing three functions of the form f(x)=sin(bx),g(x)=sin(cx),h(x)=sin(dx) where b,c,d are numbers that the user should be able to choose. The values for b,c,d should be contained in cells B2, C2, D2. The x-values should be spaced apart by the value contained in cell E4 and should be contained in cells A4-A24. The values for the function f(x)=sin(bx) should be contained in cells B4-B24, the values for the function g(x)=sin(cx) should be contained in cells C4-C24 and values for the function h(x)=sin(cx) should be contained in cells D4-D24. You can merge several graphs into one block by selecting the cells A4-D24 and then clicking on Insert and Chart. Your result should look like this:
