HOW TO USE VIRTUAL SCIENTIFIC CALCULATOR HOW IT WORKS


EXAMPLE 1: Simple Arithmetic: Simply follow the sequence

To evaluate: 50 + 45 x 3
Enter as follows: 50, +, 45, *, 3, =

To evaluate: 50 x 45-2
Enter as follows: 50, *, 45, -, 2, =

To evaluate: 25 x (5+5)
Enter as follows: 25, *, (, 5, +, 5, ), =


EXAMPLE 2: To evaluate function(value), enter value followed by function

To evaluate: 2 + log(20) x 5
Enter as follows: 20, log, *, 5, +, 2, =

To evaluate: log(30) x 5 - 7
Enter as follows: 30, log,*, 5, -, 7, =

To evaluate: In(25) x 2 + 5
Enter as follows: 25, In, *, 2, +, 5, =

To evaluate: 5 + In(25) x 2
Enter as follows: 25, In, *, 2, +, 5,=

EXAMPLE 3: sin(Degree), cos(Degree), tan(Degree):

Select Deg
To evaluate: sin(45) or cos(45) or tan(45)
Enter as follows: 45, sin or cos or tan

To evaluate: tan(45) x 5 + 2
Enter as follows: 45, tan, *, 5, +, 2, =


EXAMPLE 4: yroot() value:

To evaluate: 4th root of 5
Enter as follows: 5, y√x, 4, =


EXAMPLE 5:cube() value:

To evaluate: 563 x 6+8
Enter as follows:56, X3, *, 6, +, 8, =

EXAMPLE 6: π value:
