Homework Statement
i = 15 sin(100π.t + 0.6)
a) I need to state the initial phase angel in rads and degrees.
b) I also need to work out current at first maximum value.Homework Equations
i=A*sin(ωτ+∅)The Attempt at a Solution
a) ∅=100∏*0+0.6
∅= 0.6 rads. ∴0.6*180/∏=34.37746771°
b) first current...

I need to find x from (3.4)^2x+3=8.5
what i have done is as follows
3.4^2x = 11.56
3.4^2x+3 = 14.56
8.5 - 14.56 = x
x=-6.06 <<<<is this the correct way of solving and correct answer??
