Question about Texas Instruments TI-89 Calculator
I cannot figure out how to square or cube the cosh function or the others i.e. csc, sin, cos, etc. Is there a way to do this.......
1) Selecting the sin/cos/tan key results in sin( or cos( or tan( being displayed on your computer, 2) press [in succession] x,).
Your calculator should now be displaying cos(x). Recall that the typed cos^2(x) means that the result of cos(x) is squared. Simpler: typed cos^2(x) = (cos(x))^2.
Continuing from above: 3) press the left arrow [<-] until the cursor is on the left side of cos(x), 4) add another "(", 5) now press the right arrow until the cursor is on the far right side of what is now (cos(x), 6) add a ")" here (you should now have (cos(x)), 7) now press the ^ and 2 (you should now have (cos(x))^2), and
7) PRESS Enter and Whalaaaa
