Converting Angle To Coordinates

Hi, I need a formula, algorithm or a function("Visual Basic") that can take a position(X, Y), an angle(0-360) and a number, and based on these values it will give you a position(X, Y).
For example if I say:

Position: 1, 1
Angle: 90
Number: 2

it will return 1, 3, cause 90 degrees is up and 1, 3 is 3 steps from 1, 1.

Or another example:

Position: 1, 1
Angle: 180
Number: 7

it will return -6, 1. cause 180 degrees is left and -6, 1 is 7 steps from 1, 1.

newx = oldx + length * cosine(angle)
newy = oldy + length * sine(angle)

A is your oldx,oldy .... B is the new location newx,newy .... you are given the angle CAB and length AB (denoted by H)

basically H - hypotenuse ... A - adjacent ... O - opposite

clearly co-ordinates of C are newx,oldy
also newx = oldx + A

now Cos(CAB) = A/H
or A = cos (CAB) * H
therefore newx = oldx + cos(CAB) * H

same applies to newy which will evaluate to
newy = oldy + H * sin(CAB)

For this

Position: x, y
Angle: t
Number: n

As a subroutine

Sub newpos(x,y,t,n)
newXpos=x + round(n*cos(t))
newYpos=y + round(n*sin(t))
End Sub

or as a pair of functions

Function  newXpos(x,y,t,n)
newXpos=x + round(n*cos(t))
End Function

Function  newYpos(x,y,t,n)
newYpos=y + round(n*sin(t))
End Function
