Maths wizz only thanks

This is what I getting with vb code..

Degrees
X1 and Y1 are static for testing
X2 and Y2 are calculated.

ALL X and Y are pixels

X2 = X1+100 pix

Y2 = ??


Dim Angle As Double = (Levels(k) * Math.PI) / 180
Dim y2 As Integer = CInt((100 * Math.Tan(Angle)))

This is what I get ...(NOT Trendlines are converted to rays)

NOTE: Chart is a even box so scalling is nullified.

HI,

I have the angle in degrees ( like 22,45,67,75), I also have the length of 100 for the bottom black line.


How do I calculate the LENGTH of X (ie dotted red line)

I forgotten SIN, COS, TAN..

Please advise...thanks

Go to wolfram alpha. Type 100tan(angle).

Approx. 236 for 67 degrees

are you working in Excel / VBA? If so, the code =RAND() should give better results than your super dooper angly thingy me jig. Try it out. All other programming languages have formulas that will work as well. You also can construct a quite serviceable analog proxy using some common household items.

Please, let me encourage you to thoroughly test the angley concept before you actually trade it. Please.
