uTo perform an integration calculation

Example To perform the integration calculation for the function

∫

(2x

+ 3x + 4) dx

Input the function

f (x).

AK4(CALC)4(∫dx)cvx

+dv+e,

Input the start point and end point.

b,f,

Input the number of divisions.

• In the function f(x), only X can be used as a variable in expressions. Other vari-

ables (A through Z, r,

) are treated as constants, and the value currently as-

signed to that variable is applied during the calculation.

• Input of

n and the closing parenthesis can be omitted. If you omit n, the calculator

automatically selects the most appropriate value.

• Calculation precision is theoretically ±1 at the least significant digit of the dis-

played result.

k Application of Integration Calculation

• Integrals can be used in addition, subtraction, multiplication and division.

Example

∫

f(x) dx +

∫

g(x) dx

• Integration results can be used in addition, subtraction, multiplication and divi-

sion, in functions.

Example 2 ×

∫

f(x) dx, log (

∫

f(x) dx)

• Functions can be used in any of the terms ( f(x), a, b, n) of an integral.

Example

∫

cos 0.5

(sin x + cos x) dx =

∫

(sin x + cos x, sin 0.5, cos 0.5, 5)

sin 0.5
