What is the period of a trig function?
The period of trigonometric function is the distance between repetitions of the function. The "x" value of the space it takes to start over.
What is Osborn's rule?
It is used in hyperbolic functions; it's the rule to change a normal trig function into hyperbolic trig function. Example: cos(x-y) = cosx cosy + sinx siny Cosh(x-y) = coshx coshy - sinhx sinhy Whenever you have a multiplication of sin, you write the hyperbolic version as sinh but change the sign. also applied when: tanxsinx (sinx)^2 etc... Hope this helps you
What is mean by non-sinusoidal load?
A load that is not sinusoidally varying (i.e. resembling that of a graph of the function sin(x) or cos(x)). This means the load is not cycling or periodic so it does not repeat itself over and over - which is exactly what the graph of the trig function sin(x) demonstrates.
Sine divided by cosine?
Trig identity... sin/cos = tangent
What is harder pre calculus or Trig?
Depends on the person but for me it was pre cal dude
