How do you solve this equation for t: 0 = 50sin^2(t) + 43.275sin(2*t) - 6.517

[From: ] [author: ] [Date: 12-06-28] [Hit: ]

517 = 0 -----> 25cos(2t) - 43.275sin(2t) =18.---> 49.98 cos(2t+ 1.047) = 18.483 ,......

Working on engineering homework and I need to solve this equation. Can't think of which trig identity to use. Wolfram Alpha was no help =[

Solve for t (angle)
0 = 50*sin^2(t) + 43.275*sin(2*t) - 6.517

25 - 25cos(2t)+43.275sin(2t) -6.517 = 0 -----> 25cos(2t) - 43.275sin(2t) =18.483
---> 49.98 cos(2t+ 1.047) = 18.483 , then it's easy to solve
