If anyone has a TI-nspire calculator (CAS or CX), Then I can show you how to make a flower in the graph part

Here are the steps

Turn on the calculator

Open a graphs page

Hit tab

Hit menu

Go to Graph Entry/Edit (for a CX it will be #3)

Select Polar (for a CX it will be #5)

Type in the blank n sin(a θ)

You can replace sin with cos

Boom you have a flower

Remember n and a are numbers you pick. n can be negative. θ is like the x in a rectangular graph, but can’t be replaced with x. θ can be found by pushing the pi button, and selecting the weird circle with a line through it (it’s a Greek letter).

Congratulations you just made a rose curve in your calculator! It is a polar curve graph that makes a flower! If you want another fun graph, you can look up the butterfly curve! Have a nice day!

Luigi Guido Grandi born on 1st October 1671 was an Italian monk, mathematician and engineer. He has done a lot of incredible things for math, one of them is studying the rose curve (sin wave plotted in polar coordinates), a curve which has the shape of a petaled flower. He named the rose curve rhodonea.
