Scientific Calculator Created Using Visual BasicThis is a calculator that resembles a typical scientific calculator , albeit a simpler version. In our version, we have only included the trigonometric functions and the logarithmic functions. The reason of creating a simpler version of the calculator is to help users to learn the programming concepts in a gradual manner and not to confuse them especially those who are learning to program in Visual Basic.To design the interface, we just to need to modify the interface of the basic calculator that we have created earlier using Visual Basic 6. In this calculator, we have added five more buttons, they are Sin, Cos, Tan, Log and Ln. The common trigonometric functions in Visual Basic 6 are Sin, Cos, Tan and Atn.a) Sin is the function that computes the value of sine of an angle in radian.b) Cos is the function that computes the value of cosine of an angle in radian.c) Tan is the function that computes the value of tangent of an angle in radian.d) Atn is the function that computes the value of arc tangent of an angle in radian.Log computes the value of logarithm to base 10 whilst Ln computes the value of natural logarithm.An angle in degree has to be converted to radian before it can be calculated by the above trigonometric functions. From high school mathematics, we know that π radian is equivalent to 180°; which means 1 radian is equivalent to π divided by 180. Therefore, in order
