It works great on your phone - full screen if you add it to your homescreen.
Example in C :
Calculate (3+2i)*(1+4i)
C
(3+2e1)
*
(1+4e1)
=
answer is -5+14e1
Example in D
Calculate the value of the function and first derivative at x=3
f(x)=x3-2x2+3
D
3+e0
STx1
Clx1*x1*x1-2*x1*x1+3
=
answer is f(3)=12 and f'(3)=15
Example in spacetime M
You see two simultaneous lightning strikes in 10 microseconds, one where you are, one 20 km in the x-direction.
Are these events simultaneous for a spaceship flying at 0.5c in the x-direction? (given : atanh(0.5)=0.5493)
M
0.00001e1
STx1
+20e2/300000
STx2
Cl(0.5493*.5e1e2)Exp
STx3
Clx3*x1*x3x̄
STx4
Clx3*x2*x3x̄
STx5
answer is strikes happen at (X4 : 11ms) and (x5 : -26ms) - not the same time.
