How to integrate a function (Definite Integral)

Model : CASIO fx-570MS, CASIO fx-991MS

Calculator can easily perform definite integration (integration with limit). Mainly three inputs are required for the operation.They are a function with variable x, lower limit, upper limit.

Example: What is the value of  ∫₂⁵(x³-5x-3)dx ?
              Options: a) 129/12, b) 363/4, c) 65/7, d) 1/2

Constant and Conversion

Model : CASIO  fx-991MS
Often we use different constants such as Plank Constant ( h = 6.63*10^-34 Js ), Mass of Electron ( m_e=9.11*10^-31 kg) etc in calculation. It is difficult to keep in mind such values all the time. Calculator has kept stored such constant values in it's memory.

Example: What are the values of Plank Constant and Charge of an Electron ?(Ans: h=6.63*10^-34 Js and e=1.6*10^-19 C )

How to find the values of a function for different input simultaneously(Calc Memory))

Model : CASIO fx-570MS, CASIO fx-991MS
CALC memory(CALC button) lets you temporarily store a mathematical expression that you need to perform a number of times using different values.Once you store an expression,you can recall it, input values for it's variables and calculate  a result quickly and easily.

You can store a single mathematical expression with up-to 79 steps.CALC memory can only be used in the COMP and COMPLX Mode.

Example: Calculate the result of  y=a²+b²+c²+3abc when
                                                a) a=5,b=2,c=1 (Ans:60)
                                                b) a=3,b=7,c=4 (Ans:326)
