5. Numerical Calculations

The following explains the numerical calculation operations included in the function menu displayed when K4(CALC) is pressed. The following calculations can be performed.

{Int÷}/{Rmdr}/{Simp} ... {quotient}/{remainder}/{simplification}

{Solve}/{d/dx}/{d2/dx2}/{dx}/{SolveN} ... {equality solution}/{first derivative}/{second derivative}/{integration}/{f(x) function solution}

{FMin}/{FMax}/{Σ(}/{logab} ... {minimum value}/{maximum value}/{summation}/{logarithm logab}

kQuotient of Integer ÷ Integer[OPTN]-[CALC]-[Int÷]

The “Int÷” function can be used to determine the quotient when one integer is divided by another integer.

Example

To calculate the quotient of 107 ÷ 7

AbahK4(CALC)6(g)

6(g)1(Int÷)h

w

kRemainder of Integer ÷ Integer[OPTN]-[CALC]-[Rmdr]

The “Rmdr” function can be used to determine the remainder when one integer is divided by another integer.

Example

To calculate the remainder of 107 ÷ 7

AbahK4(CALC)6(g)

6(g)2(Rmdr)h

w
