cant be closer than this!

i thought there must be something addition of two "sin"s and their coefficients should be different from each other. this solution makes me happy...

thank you...

but i want to know how can you produce a polar coordinated graph in excel? - Mar 14th 2010, 01:43 PMGrandad
Hello springI'm using a fairly old version of Excel. (I bought Office 2007 and tried to like it but hated it, so I reverted to my earlier 2000 version.)

1. Set up two columns of values: and . Use values of from to .

2. Create two further columns and .

3. Use the XY (Scatter) graph-type using the and values, choosing the 'smoothed lines without markers' sub-type.

hmm, got it!

excel is incredible sometimes.

i will try to produce the equation by skeeter.

by the way,

Hi there, first post, i'm in the middle of doing that very design but my clover isn't as tidy as yours, just wondering what i'm doing wrong.
