# How do you label the x-axis in terms of pi?

I am supposed to change the x-axis units to multiples of pi/2 with the axis labeled in terms of pi.

### I am getting the wrong answers with the tan -1 function

Hello,
That habit of TI, Casio, and Sharp to label the inverse trigonometric functions with the -1 superscript can cause confusions.
1. The inverse trigonometric functions arcosine, arcsine, and arctangent (labeled by manufacturers as cos^-1, sin^-1, and tan^-1) should not be confused with the other trigonometric functions known as secant(x) =1/cos(x), cosecant(x)=1/sin(x) and cotangent(x) = 1/tan(x).
2. To avoid errors in the use of the inverse trigonometric functions, one must be careful and set the angle unit to the one required by the problem at hand (degrees, or radians)
3. To make the trigonometric functions really functions, their range is restricted.
4. In this calculator arcosine (x) gives results between 0 and 180 degrees (if angle MODE is Degree) or between 0 and Pi radians (if angle MODE is Radian).
5. The range of results for arcsine(x) and arctangent(x) is between -90 degrees and +90 degrees (if angle MODE Degree) or -Pi/2 and Pi/2 (if angle MODE is Radian)
With this information you should be able to set the angle unit correctly ([MODE][Radian] or [MODE][Degree] ) and interpret the results. If you want to extend the angle to other values, use the periodicity of the trigonometric functions.

Hope it helps

### Admission to a professional course is subject to the following condition: a) Marks in mathematics > = 60 b) Marks in Physics > = 50 c) Marks in Chemistry > = 40 d) Total in all three subjects >...

So:

X >= 60
Y >= 50
Z >= 40

Take 51 sheets of "graph-paper" (1+200 minus 60 minus 50 minus 40).

On the first sheet of paper, label the graph-title as 'Z=40'.
Label the X-axis from 60 to 200.
Label the Y-axis from 50 to 200.
Draw a straight line from (X=60 and Y=(200-60-40))
to (Y=50 and X=(200-50-40)).

On the second sheet of paper, label the graph-title as 'Z=41'.
Label the X-axis from 60 to 200.
Label the Y-axis from 50 to 200.
Draw a straight line from (X=60 and Y=(200-60-41))
to (Y=50 and X=(200-50-41)).

On the next sheet of paper, label the graph-title as 'Z=42'.
Label the X-axis from 60 to 200.
Label the Y-axis from 50 to 200.
Draw a straight line from (X=60 and Y=(200-60-42))
to (Y=50 and X=(200-50-42)).

On the second sheet of paper, label the graph-title as 'Z=43'.
Label the X-axis from 60 to 200.
Label the Y-axis from 50 to 200.
Draw a straight line from (X=60 and Y=(200-60-43))
to (Y=50 and X=(200-50-43).

Keep going for all 51 sheets of graph-paper.

Stack the 51 sheets on top of each other,
to visualize the "3-D" solution to the problem.

P.S. Don't tell your school-teacher that I helped you do your "homework".

### My printer display keep showing " Warning, Ribbon in", cannot print multiple label at a time

i have the same problem , but my printer is ZEBRA S4M ZPL

my solution is:

in your barcode software: change printer settings: 1 and 2

1 . in media setting : change media type --> Thermal transfer
2. in documents options , configuration --> use printer settings
