Radians in math actor

[particlep]

i'm using the equation y=sin(2πt/23) and have been experiencing unexpected results.

after much head scratching and googling, i've realised the problem is that i'm sending in a radian value into the math actor and this is treating it as a decimal value.

i don't know wether i need to make the math actor work with radians or if i need to convert the radian value to a decimal.

i've found what to do.

y=sin(2pi X t / 23) X 180 / pi 

the answer is in degrees and the math actor works in degrees.

yesterday i might have been having a bit of what we'll call in the uk "a bit of a blonde moment"
