Let use an example to convert from polar to rectangular. There may be other ways to do it on this particular calculator, but this should work on all calculators.

Let's use 20 degrees and 5 units for our polar.

Sin 20 degrees = y/5, cross multiplying we get y = 5 sin 20 degrees.

Similarly, Cos 20 degrees = x/5. Cross multiplying we get x = 5 cos 20 degrees.

Thus, I get (1.71, 4.70) as the rectangular coordinates of the point.

Good luck.

Paul

If you are talking about the multiplication sign, look for a key marked with a cross. It should be in the same column as the other operations, between the subtraction (-) and the division keys.

All objects have limitations and this calculator has some of its own. What can we do about it?

Reopen one vector (or even the two vectors) you stored and edit it (them) then perform the vector product.

FINALLY figured out how to change the tax rate! Press AC. Press and hold the Rate Set (%) button __UNTIL THE CURRENT TAX RATE IS DISPLAYED__. Enter the new rate you want (such as 7.5). Press the Rate Set (%) button again.

Here is a solution.

Graph the function over the domain [-Pi,+Pi]

Then press the [SHIFT][MENU] (SETUP) and in option [Dual Screen] select [G to T] Graph to table. The screen will be spilt in two, but the Table part remains empty.

Press [SHIFT][F1] (TRACE), the cross hair appears on screen.

Move it around on the curve

If you press [EXE] at a cross hair location, the table records the X and Y value. On the following screen capture, the exponential function is graphed along with sin(X) and the table is populated by selected values of the exponential.

Now rate all the solutions I provided for you

It is a spurious effect due to drawing **connected plots**. It joins the last point on one side of the asymptote to the first one on the other side. To deal with this spurious effect, one should

- draw
**dotted plots**, or - ignore the segment that crosses the asymptote.

assuming the question is what is the circle equation?

and if (-2,2) is the center of the circle

the equation should look like this: (x+2)^2+(Y-2)^2=R^2

And now only R is needed.

given 2x-5y+4=0 equation of line perpendicular

we can rearange the equation to be y=(2x+4)/5

from that we can see that the slope of the line is 2/5

And from the fact of perpendicular line we can say that the slope

of the radius line is -2/5.

The motivation now is to calculate the distance between the center of the circle to the cross point of the radius with the line perpendicular

For that we would calculate the radius line equation and compare it to the equation of line perpendicular

As mentioned earlier the slope of the radious line is -2/5.

So the equation is y=-2/5x+b and b can be calculated by using the center of the circle coordinates

2= - (2/5)*(-2)+b ------> b=2-4/5=1.2

radius equation is y=-(2/5)x+1.2

Now the cross point is calculated by comparing the equations:

-(2/5)x+1.2=(2x+4)/5 --> -2x+6=2x+4 --> 4x=2 --> x=1/2 --> y=1

So the cross point is (1/2,1).

The distance between the points is calculated by the following

Formula:

R=SQR(((1/2)-(-2))^2+(2-1)^2)=SQR(2.5^2+1^2)=SQR(6.25+1)=

SQR(7.25)

Therefore the circle eq is (x+2)^2+(Y-2)^2=7.25

and if (-2,2) is the center of the circle

the equation should look like this: (x+2)^2+(Y-2)^2=R^2

And now only R is needed.
