i have a math problem that i do not really understand :
sin²x - 0,64 = 0
the answer in the back of the book says that it's 0.93 .
i dont understand how they got to that answer because i thought that to solve it , you had to do the square root of sin²x and of 0,64 since the are both perfect squares.
