sin(60) or sin(PI/3) = sqrt(3)/2
cos(60) or cos(PI/3)=1/2
tan(60) or tan(PI/3) = sin(60)/cos(60)=sqrt(3)
But we want tan for -sqrt(3). Tangent is negative in quadrant II and IV.
In Quadrant IV, we compute 360-60=300 or 2PI-PI/3 =5PI/3
tan(5PI/3) = -sqrt(3)
Tangent is also negative in the second quadrant, so we compute PI-PI/3=2PI/3 or 120 degrees.
tan(t)=-sqrt(3)
t=5PI/3 or 2PI/3
The period of tan is PI
The general solution is
t = 5PI/3+ n PI, where n is any integer
t = 2PI/3+ n PI, where n is any integer
y = 2x is defined everywhere (for all values of x)
True
x2+2x+1=y or y=x2 In this function the domain is x equals real values and the range is y equals all real values provided y is more than or equal to zero.
It is, in fact, an identity - which is an equation which is true for all values of the variable.
That would be because all the graphed values of x are 4. So you can plug anything in for Y and it will still be on that vertical line.

It means that the observed values in the experiment all exactly match the expected values. That is unlikely, unless the experiment was "fixed".
that would be limited to 3 and -3 for values of x

7/4 equals 1 3/4 (or 1.75) - these are all equivalent values.
X=60 how did you get that? could you show all the steps?
All of the above. I forget the exact amount, but a couple of bytes equals a kilobyte, a couple of kilobytes equals a megabyte, a couple of megabytes equals a gigabyte, and a couple of gigabytes equals a terabytes. You can even go further by saying a couple of terabytes equals an exobyte.
A specific value for the mode cannot be given with the information provided. The arithmetic mean = Sum of all the values ÷ The number of values. The median is the value which lies halfway along the series when arranged in ascending or descending order. The mode of a set of values is the value which occurs most frequently.
The slope is infinite because x = 2/3, a vertical line, for all values of y.
