# How do you graph #r=10sin4theta#?

##### 1 Answer

See explanation and graph.

#### Explanation:

As r is non-negative, so is

only half of every period.

Four loops are created for

See graph depicting these aspects now, for the converted

equation, using

graph{( x^2 + y^2 )^2.5 - 40 (x^3y - xy^3 ) = 0 [ -20 20 -10 10]}

I think, after reading again and again that scalar

answers, the centuries old practice of showing ( 4 r-positive + 4 r-

negative ) 8 loops, for this equation, is given a go.
