WebConsider the current I=I(m)sin(wt) and Voltage V=V(m)sin(wt+pi/2)= v(m)cos(wt). What this phase difference signifies is that if you start the circuit at t=0, then the voltage at t=0 v=V(m) while i=0, meaning the circuit will gain maximum voltage value before the maximum current value is reached.

WebIt is also true that cos (½π-x) = sin (x) and that cos (x- ½π) = sin (x) So, cos (½π-x) = cos (x- ½π) Sine and cosine are both periodic functions that are identical except for being shifted ½π radians out of phase. Thus, there are a number of ways you can shift them around to be in phase and therefore equal.

WebYou can use either sin(wt) or cos(wt) to indicate the start of the phase. The only difference is that the cos phase is shifted 90o (pi/2) compared to the sin phase. Generally cos gives the x-coordinate of the instantaneous value and sin gives the y-coordinate of the value. Both can be converted to the other using standard trigonometric identites

Websin α = side opposite hypotenuse and cos β = side adjacent hypotenuse. Notice that the side adjacent to β is the same as the side opposite of α, thus sin α = cos β. In addition, since this is a right triangle, α + β = π 2.
