If tan(theta)= -10, sin(theta)<0, find the exact value of each of the following for 0≤theta<2π. A. sin(2theta) B. cos(2theta) C. sin theta/2 D. cos theta/2

Sorry, I couldn't find the symbol for theta!!! :(

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
