Homework Statement
The instantaneous value of current, i amp, at t seconds is given by:
i = 15 sin(100π.t + 0.6)
Find the value of;
a) amplitude
b) period
c) frequency
d) initial phase angel
e) value of i when t = 2.5s
f) time when current first reaches maximum value
Homework Equations
i=A*sin(ωτ+∅)
i = A.sin(2pi.f.t + ∅)
The Attempt at a Solution
I understand from looking around these are the correct formula to use, is someone please able to explain how to arrive at the formula from question statement i = 15 sin(100π.t + 0.6)? having some difficulties understanding the math involved. Thanks.
