Question

solve : sin squared 2x = 1

Answer 1

take square root of both sides

sin(2x) = 1
sin(2x) = -1

can you do it now ?

Answer 2

tnx

Answer 3

what is the final answer?

Answer 4

2x=1
divide both side by 2
x=1/2

check:
2(1/2)=1
2/2=1
1=1
so the answer is correct

Answer 5

sin(2x) = 1 -> 2x = 90 + 2*pi*n -> x = 45 + pi*n
sin(2x) = -1 -> 2x = 270 + 2*pi*n -> x = 135 + pi*n

-> x = 45 + (pi/2)*n
