cos(u) = -5/13 tan(u) = 12/-5 sin(-u) = -12/13 cos(-u) = 5/13 tan(-u) = 12/5 sin(u+pi) = -12/13 cos(u+pi) = 5/13 tan(u+pi) = -12/5 sin(u+(pi/2))...
A power failure on the bridge of a Great Lakes freighter has resulted in the ship's navigator having to do her own calculations. She measures the angle between the ship's course and a lighthouse on...
It is impossible to measure the length of a particular swamp directly. (Snapping turtles!!) Kendra put a stake in the ground and measured from the stake to opposite ends of the swamp, the results...
sin(u+pi) = cos(u+pi) = tan(u+pi) = sin(u+(pi/2)) = cos(u+(pi/2)) = tan(u+(pi/2)) = I figured out the first few but this +pi stuff...

Find the angle x such that 0 is less than or equal to x which is less that 2pi. cos(2x)= =2-2sin^2x
This is a trigonometry identity equation.
I dont have to show any work......
How do I solve this? I never learned how to solve limits with trig functions
