c4t needs to be with no dimensions to be inside of the cos.
Need some help with some physics problems. The counselor ruined my schedule and didnt give me trig so i technically shouldnt be in physics but they let me in. Anyway the problems are :
Find the dimensions for the quantity c4 in s=c3 cos(c4t) and t = T for time and L = length, s=L
L=c3 cos(c4T)
the c3 and c4's are c with the subscript number next to it
Also there is something about a Cartesian plane that I can't make much sense of:
The Cartesian coordinates of a point in the xy plane are x=-3.34m, y=-3.26m. Find the distance, r, from the poin of origin. Answer in units of m. Then calculate the angle Θ between the radius vector of the point and the positive x axis(measured coutnerclockwise from the positive x axis, within the limits of -180° and + 180°). Answer in units of °.
