A sine wave with a frequency of 10Hz and an amplitude of 5 units phases from zero to 2π radians in a complete cycle. How long does it take for the phase to reach a value of π radians?
y(t) = A . sin (2.π.f.t + φ)
0.1 = 5 x sin (2x∏x10x time + 3.14)
time = 0.038 seconds
But the answer suppose to be 0.005 and I got 0.038.
Thank you!
