# How do you change polar coordinates to rectangular on a TI 84?

To convert between polar coordinates and rectangular coordinates (r, θ, where r>0) see the inverse trigonometric functions -arctan() and arctan().

## How do you find polar coordinates from rectangular coordinates?

When you need to find the distance of a point from a straight line, use the distance of the point from the line. The distance from the line is the magnitude of a vector: x1y2.

## How do you get decimals on a TI 84?

How to get a decimal on your TI-84 Plus Calculator The correct order is to find 1 (1 decimal) and then multiply the 1 number by the decimal point number. This process gives you a decimal answer. To solve the problem 4.98 – 3.78 ÷ 5.2 ÷.15 =? (2.) Find the answer: 5.18 ÷ 0.15 = 32.971 ÷ 5.2

## Accordingly, how do you change a fraction on a TI 84 Plus?

The rules for changing a fraction on the calculator follow: 1. Put the calculator in decimal mode.

## How do you change from imaginary to Polar on a calculator?

To get the imaginary unit, first set one column to imaginary, enter i, hit Enter and enter a number. Now type “i i” to get the polar unit. Alternatively, you can enter “e” in any field and hit enter. In the exponent field, type i.

## How do you change from rectangular to Polar on a TI 83 Plus?

The method is just like in the regular calculator. When switching from square to Polar mode, press QQQQ and the numeric keypad will appear instead of the square root key. Then press ZZQQZQ and you will get a polar square root key.

## How do you graph R on a TI 84?

Graph R on the calculator by dividing both sides of the ratio of (x + 1)(x + 2) by the product of x and its power. x + 6/x-2.

## How do you convert complex numbers to polar form?

To convert complex numbers into polar form, multiply both the real part and the imaginary part by the square root of -1. If r is the real part of z, then r· r = -1·r and i·i = -1·i = i·i.

## Where is Theta on a graphing calculator?

Theta is usually shown right under Riemann Zeta. Theta is not always under Riemann Zeta, because you might not always have the graph of zeta. However, you should have zeta.

## How do you make a flower on a graphing calculator?

1. Draw an axis along the main y-axis on your graphing calculator. Then draw a line across the line. Type in 2 in your calculator and set your calculator axis to y-axis. Now type 0 in your calculator and hit the button F9 (equivalent of *1).

## Secondly, can TI 84 Plus do complex numbers?

It depends on the textbook you bought. The TI 84 Plus CE can do complex numbers, just like some of the TI calculators at the high school level can do complex numbers, but the TI series is generally limited to the functions required for the C++ program.

## How do you graph polar equations by hand?

First write the two coordinates in radians. Add the angle in the first equation to get all the angles from the first equation. Use the second equation to get the radian in the second equation. Finally, use the new coordinates to draw the graph on your lined paper.

## How do you change a fraction to a decimal on a calculator?

Press 1 then 2. The cursor will blink to indicate that the decimal is being entered into the calculator. Press 1 (right arrow) or 2 (left arrow). After inputting the decimal, press the Clear key.

## Simply so, how do you enter polar coordinates on a TI 84?

TI84 has a calculator with polar coordinates. To enter the coordinates on your calculator, find a place on the number line in the usual way by pressing the 2 button and pressing 9 to select the number line from 1 to 10. Then you enter the radius by plugging the number into the r field of the calculator and you enter the angle by pressing the 8 button and selecting the unit of measure from degrees to radians.

## How do you change a decimal to a percent?

If the decimal is a percentage, multiply it by 100: 100.000 or more, divide by 100: 0.100 or less. Examples of decimal percentages are.02% and.98%. If the decimal is a fraction, divide it by the value of the whole: 100 or more, divide by 100: 0.02 or more, divide by 100: 0.02 or less.
