Q3] (10 Marks) Convert the following arithmetic formula to visual Basic Language formula: e + sin 30 -b + V6² – 4*a*c log(2) - tan(35) 2- 2*a 1-

Answer 1

To convert the arithmetic formulas and implement them in the Visual Basic Language formulas, we need to use the System.Maths class which contains different mathematical functions such as square root, logarithm (log), trigonometric functions, and other mathematical functions. The following are the Visual Basic language formulae for their corresponding arithmetic formulas:

• e⁵ - Math.Exp(5)
• sin 30 - Math.Sin(30)
• log(2) - Math.Log(2)
• tan 35 - Math.Tan(35)
• For square root - Math.sqrt()

Hence, using the System.Maths class, we can use the above different math functions to convert the required arithmetic formulas into Visual Basic language formulas as given below. Note that simple arithmetic operations such as +, -, *, / remain same in the VIsual basic language too, as in the normal arithmetic formula representation. However, we use the ^ operator which is also known as the exponentiation operator and is used to raise a number to a specific power like 2^2 = 4, 27^1/3 = 3, etc.

Here are your answers for the two part asked in the question:

1: ( ( Math.Exp(5) + Math.Sin(30) ) / ( Math.Log(2) - Math.Tan(35) ) )^1/3

Note that here in this part, we use the ^ operator to cube root (1/3) the whole formula at the end as it is stated and required in the question where the whole term is cube-rooted in the arithmetic formula.

2: ( -b + Math.Sqrt(b^2 - 4*a*c) ) / 2*a

Note that here in this part, we use the Math.Sqrt() to implement square root (1/2) as it is stated and required in the given arithmetic formula. The Math.Sqrt can be hence simply used to square root a number.

Thanks!
