The calculator does not have a Computer Algebra System or CAS: It cannot handle non numerical quantities. Every letter symbol must have a value stored in it prior to being used. If no value is stored in a letter symbol, value 0 is assigned to it. Sorry. As to calling Pi a variable, I would not got that far, even if the calculator would give me 2Pi. TI calculators that have a CAS are the TI92 Plus, the Voyage 200 PLT, and the TI Nspire CAS, TI Nspire CX CAS.
Well it depends. If the hexagon is irregular (sides are not equal) there is no formula to calculate the sides as they can have arbitrary values. You must measure them. If the hexagon is regular you may be able to relate the measure of a side to the radius of the circle in which it is inscribed. If you have the radius of the circle, the side is equal to the radius. If you have the value of perimeter you divide that value by 6. There is also a formula that relates the area of the hexagon to the measure of the side s. The formula is Area=(6/4)(s^2)cot(PI/6), where cot is the cotangent function, its angle is in radian. In degrees Pi/6 is 30 degrees.
Pi is a mathematical constant whose value is the ratio of any Euclidean plane circle's
circumference to its diameter; this is the same value as the ratio of a
circle's area to the square of its radius. It is approximately equal to
3.14159265 in the usual decimal notation.
The tangent function (and the cotangent) are periodic, with a period of pi. The calculator will give you a result from -pi/2 to pi/2, while the Hawkes apparently is giving you a result from 0 to pi. The difference between 2.1588 and -.98279 is pi.
To make the calculator's result match Hawkes, if the (co)tangent gives you a negative value, simply add pi to it.
No the calculator cannot do that.
But if you do [2nd][Pi] [EXE] then just after [2nd][tan-1][2nd][Ans] you get 1. If you use the inverse trigonometric functions you will never have a value such as pi/4 or pi or pi/2. If angle unit is set to degrees you recover the exact values of the angles (they are integers anyway.
Hope it helps.
