I have this question:
"A particle initially 4 metres to the right of the origin, has a velocity in metres per second (m/s) given by:
Find the expression for the displacement of the particle as a function of the time and hence find when the particle first passes through the origin"
So when i find t do i find it with the calculator on degrees or radians? see in radians it first passes through the origin at 1 second, but in degrees it first passes the origin at 57.29577951
