Please help me understand how my professor solved this and plugged in the values

Problem 1: You are given the following AC wave. 10.0 . sin 28.25 . t+ , please identify 2 (a) the Amplitude of the wave (b) the phase of the wave indegrees, (c) the angular frequency and (d) the frequency. AQ:= 10.0 TT D : =90 deg 2 rad Wo:= 28.25 sec Wo fo =4.496 2 - 71 S
