Use trigonometric identities to solve each equation within the given domain. a) -sin^2(x) = cos(2x) from [-1, 1]
b) 3tan(x)=2sin(2x) from [0,2π)
c) sec(x) cos(3x)=0 from [-π/2,π/2]
d) 1-cos(x)=2-2sin^2(x) from (-π,π)
e) 4cos^4(x)-5cos^2(x)+1=0 from [0,2π)

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.

the end. : )
