How do you make a shape on a graphing calculator?

In order to make most (recognisable) shapes on a graphing calculator, you will need to use at least 2 graphs mapped onto the same set of axes. For example, to make a heart, you havce 2 equations - Y1 and Y2 where:

Y1=(3/2)x^(2/3)+√(20-x²)-3
Y2=(3/2)x^(2/3)-√(20-x²)-3

This will give you what looks very much like a Valentine heart shape (changing the 3/2 at the start of each part to a 2 may give a taller heart, but it is thinner and IMO doesn't look as nice - choosing a coefficient between about 1.3 and 2 would give you the best Heart shape)

There are various other shapes that can be made too, but I'm not sure how to do them off the top of my head

The easiest way is to buy from a High street shop or from Casio on Amazon. There are so many fakes on eBay and in other places online. If you buy from a shop only accept one in a box.

If you have already bought one push down all the buttons at the same time. The display should show 88:88, Also hold down the 24HR button for a few seconds and the words Casio should show on the screen.

What is the difference between casio fx-570ex plus and casio fx-991ex plus calculator?

THROUGHOUT HISTORY CASIO MANUFACTURED DIFFERENT KINDS OF CALCULATORS:
BUT THERE IS A HUGE DIFFERENCE BTEWEEN CALCULATOR IP:9983726540 OR WHAT IS KNOWN AS CASIO FX-570ex PLUS AND CALCULATOR IP:9836726391 OR WHAT IS KNOWN AS CASIO FX-991ex PLUS

FIRST CASIO FX-570ex PLUS IS MAINLY MADE IN CHINA OR MOST PROBABLY IN SIRILANKA AND YOU CAN DIRECTLY KNOW FROM THE STINKY RUSTY SMELL EMERGING FROM THIS PIECE OF GARBAGE WHICH IS MAINLY USED BY LOSERS AND GARBAGE MAN BUT ON THE OTHER HAND CASIO FX-991ex PLUS IS A HIGHLY SOPHISTICATED CALCULATOR DISIGNED ESPECIALLY FOR GREAT THINKERS AND GS STUDENTS ALL OVER THE WORLD

SECOND AND FINALLY UNLIKE FX-570ex PLUS, CASIO FX-991ex PLUS IS UNIQUELY PURCHASED WITH ITS OWN SOLAR POWER YESSS ITS OWN SOLAR POWER THAT HELPS TO INCREASE THE POWER IN ITS REMARKABLE GOLD BATTERY AND ITS SILVER BULLET PROOF CASE UNLIKE THE FX-570ex PLUS'S CASE WHICH IS MADE OF CHEEP PLASTIC PAINTED TO SEEM LIKE AN ALUMINUM FOIL

How do you use imaginary number in a scientific calculator?

Each calculator has its own nomenclature for working with imaginary and complex numbers. Many scientific calculators allow you to just type -1 and hit the square root button and it will give you something like (0,1) or (1,∠90°). In the first example, the first number {the 0} represents the real part, and the second number {the 1} represents the imaginary part. This is what happens on the HP-48 and HP-50 in Rectangular mode. In the second example, the calculator is in Polar mode (degrees), rather than Rectangular. So the first number {1} is the magnitude, and the second {90°} is the angle, measured in a counterclockwise direction from the positive real axis. 90° points straight up and is purely imaginary.

If my calculator was in radians mode, rather than degrees, then it would show (1,∠1.57) 1.57 radians is pi/2 (to 2 decimal places), which is the same angle as 90°.

An earlier calculator that I had, you first had to put the calculator in complex mode, then you had to push an extra button to view the imaginary part of the answer.

How do you work out the reciprocal on a calculator?
