Let a be pi/12 (no e at the end of pi...).
Your function is now 3 sin(a*t)
Its derivative if 3*a*cos(a*t)
That is to say 3*pi/12 *cos(pi*t/12)=pi/4*cos(pi*t/12)
Hi, i need to calculate the derivitive from the following formular:
y = 3sin (PIE * t / 12) : t is a variable and PIE is 3.14 etc
I think its: y = PIEcos (PIE * t / 12)
Or would it be: y = 3PIEcos (PIE * t / 12) ??
All help is appreciated.
