Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

There is nothing mysterious about it. Wittingly or not, you

switched the window limits.

**Examples**

Xmin=6.3, Xmax=-6.3

Ymin=3, Ymax=-3

or some other combinations.

Here is the 1st case (Xmin=6.3, Xmax=-6.3, Ymin=-3, Ymax=3).

The traced point has positive x

Complete switch. The graph looks correct but as

you can see the traced point has positive x,

and negative y.

I did not think the calculator would be that tolerant.

There is nothing to convert, because if T is a real number so is 40sin(4000T).

40sin(4000T)=40abs(sin(4000T))*sign(sin(4000T))

where**abs()** is the absolute value of it argument, and sign(sin(4000T)) is positive or negative.

So in (radius, angle) polar coordinates

r= 40 abs(sin(4000T)),

theta =(0, or PI), depending on sign(sin(4000T))

If you are trying to graph parametric functions, this calculator does not do graphs, and you need another function of T

40sin(4000T)=40abs(sin(4000T))*sign(sin(4000T))

where

What does your graph look like? Do you have the proper angular mode set?

Make sure you have the angular mode set to radians. In degree, the graph of sine(x) is nearly a straight line for small values of x.

Look for a key y= (y= editor). type in the right side of the function sin(x), press Draw or graph. After a graph is drawn, and if it is not well centred play with the Windows dimensions, or the Zoom functions.

To enter powers of trigonometric functions you must enclose the functions in parentheses and then apply the exponent to the whole. For example X1t =(sin T)^3 , Y1t=(cos T)^3 will give you a shape similar to a rhombus with concave sides. The symbol ^syands for the operation of raising to a power. The key is the one with the caret symbol ^ , and it is wedged between the xsqure and EXIT keys (third row of keys).

As regards the cotangent, use the equivalent definition cot(X)=1/tan(X).

The calculator is set up to produce exact results. If you want the expression to be evaluated put a decimal mark at the end of the 4.

to making 4 a floating point number instead of integer.

Alternatively, press the [MODE] key. Scroll down through the pages of options until you reach the line labeled Exact/Approx. When cursor is on that line, use the right arrow key to open the menu. Select [3:Approximate]. Press [ENTER] to save.

try seeing if the mode is in radians or degrees, it must be in radians

Let me know if this works
