x2
On a Casio calculator you can compute a square
x²
Example 1
To calculate 32 = 9
3 x² = 32
9.
and you get the same result with
3 ∧ 2 = 3^2
9.
3 × 3 = 3×3
9.
Example 2
To calculate (−4)2 = 16 where parentheses are needed
( (−) 4 ) x² = (-4)²
16.
Take care, because −42 = −16
(−) 4 x² = -42
-16.
Example 3
To calculate 02 = 0
0 x² = 02
0.
Example 4
To calculate sin2 (¾π) = 0,5
SHIFT π sin · 7 5 EXP = x² = Ans2
0.5
Example 5
To calculate 32 + 42 = 25
3 x² + 4 x² = 32+42
25.
and continue with √25 = 5
√ Ans = √Ans
5.
