Plotting bug.
I made a function in script "length(x,y) = sqrt((x^2)+(y^2))".
When I typed in "plot(length(x,2))".
I received this error "Error: Unexpected operator ) (char 2)"Also "plot(sin(x*0.2))" makes a sine wave with some spiky lines that aren't supposed to be there.

];In calculator:
"plot1(fract(x*2))"Error:
": Error. Undefined symbol plot1"3 votes 
Parametric plot?
"plot(cos(t*tau),sin(t*tau),0:1,0.01)" makes a circle.

Javascript recurring functions do not work
Executing the same function within a function makes a "not defined" error message

fix log function
log(8,2) returns 2.9999999...
log(32,2) returns 4.999999...
log(27,3) returns 2.999999...
log(125,5) returns 3.00000...
etc.While technically not incorrect, this makes copy/pasting tedious, etc.

Bug : Need to change to a smaller font .
Bug : on notebooks half the variables in drop down list cannot be viewed. The font is just HUGE. Need to change to a smaller font . Under the Length dropdown list, 'Speed' is the last I can see and there is no way to scroll down to view the rest of the list. I do not know what's happened because it used to be okay... now suddenly the font is extra large.
