In addition, more functions can be obtained by holding down the Option (Alt), key:

10x key	xy key
	ex key
Trignometry inverse functions	Memory keys
Clear last entry key	¹ (Pi) key
	x2 (Square) key

1Úx (inverse) key

Generally, the inverse of the function is obtained when holding down the Option button and pressing the key.

Thus the sine (sin) key becomes arcsine, the cosine (cos) key becomes arccosine, the tangent (tan) key becomes arctangent, the logarithm base10 (log) key becomes 10 x, the natural logarithm (ln) key becomes e x, the square root (Ã) becomes a square key, x 2, and the yth root of x becomes the x y (x to the power y) key.

The memory plus (M+) key becomes the memory minus (M-) key and the memory recall (MR) key becomes the clear memory (CM) key.

The three exceptions are the percent (%) key, which becomes the

¹(pi) key, the plus/minus key which becomes the inverse key, 1Úx, and the clear (C) key which becomes the clear last entry (CE) key.

The calculator window is a standard window with a title bar, close box and windowshade (collapse) box. The window is not resizable and hence there is no grow or zoom box. Clicking on the close box will quit iMalc, and clicking on the windowshade box will collapse the window to just the title bar. You can move the window around by click-dragging the title bar (ie clicking and holding the mouse down while dragging).
