Coding Tan, Sine, and Cosine

[darcey_123]

Mmmmmm bit of problem today.

I am coding a calculator except i need Tangent, Sine, and Cosine. Problem is how do i code them?? Is there a number combo for them or....yteah well how??

Any help would be Graciously accepted.

Try using the "Tan", "Sin" and "Cos" commands. I've never had call to use them but know they're there

Sin (X)
Tan (X)
Cos (X)

How would i code that for a calculator??

Those are the functions you will need.

Example:

txtResult=TAN('your number')

any way to get inverse ratios?

[Pradeep1210]

any way to get inverse ratios?

VB supports Sin(), Cos(), Tan()

The rest you can get simply as you do in maths:
Cot = 1/Tan(x)
Sec = 1/Cos(x)
Cosec = 1/Sin(x)

As in math, all others can be derived from those three functions.

Also, we all forgot Atn() which is arctangens.

Look at this page: http://www.engineering.usu.edu/cee/f...s_Examples.htm

it has great examples. It has the examples for working with trigonometry

Usually when people talk about inverse functions in trigonometry they are referring to the functions ArcCos, ArcSin and ArcTan.

Since the ArcTan function is built in, here is how to get the other two

Option Explicit
 
Const Pi = 3.14159265358979
Const PiOn2 = 1.5707963267949
 
Function ACos(x As Double) As Double
 ACos = PiOn2 - Atn(x / Sqr(1 - x ^ 2))
End Function
 
Function ASin(x As Double) As Double
    ASin = Atn(x / Sqr(1 - x ^ 2))
End Function
