Solve for t 0 lessthanorequalto t Solution10sintcost 2cost

Solution

10sintcost = 2cost interval 0<= t <2pi

5sintcost =cost\'

5sintcost - cost =0

cost(5sint -1) =0

cost =0 ----> t = pi/2 , 3pi/2 = 1.57 , 4.71 rad

5sint =1 ---> t = sin^-1(1/5) , pi - sin^-1(1/5)

t = 0.2 , 2.94

Solution : t = 0.2 , 1.57 , 2.94 , 4.71 radians
