Hi,
 Following a request, please find an action to get the Sine. I will carry one building the rest of trigo actions to voer the whole possibilities.

using UnityEngine;
namespace HutongGames.PlayMaker.Actions
{
	[ActionCategory("trigonometry")]
	[Tooltip("Get the sine. You can use degrees, simply check on the DegToRad conversion")]
	public class GetSine : FsmStateAction
	{
		[RequiredField]
		public FsmFloat angle;
		
		public FsmBool DegToRad;
		[RequiredField]
		[UIHint(UIHint.Variable)]
		public FsmFloat result;
				
		public bool everyFrame;
		public override void Reset()
		{
			angle = null;
			DegToRad = true;
			everyFrame = false;
			result = null;
		}
		public override void OnEnter()
		{
			DoSine();
			
			if (!everyFrame)
				Finish();
		}
		public override void OnUpdate()
		{
			DoSine();
		}
		
		void DoSine()
		{
			float _angle = angle.Value;
			if (DegToRad.Value)
			{
				_angle = _angle*Mathf.Deg2Rad;
			}
			result.Value = Mathf.Sin(_angle);
		}
	}
}
 bye,
