hi,
what can be the polar equation whose graph is just like a 4-leaf clover as in the attachment?
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?
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: $\displaystyle \theta$ and $\displaystyle r=f(\theta)$. Use values of $\displaystyle \theta$ from $\displaystyle 0$ to $\displaystyle 2\pi$.
2. Create two further columns $\displaystyle x = r\cos\theta$ and $\displaystyle y = r\sin\theta$.
3. Use the XY (Scatter) graph-type using the $\displaystyle x$ and $\displaystyle y$ values, choosing the 'smoothed lines without markers' sub-type.
