how would you find the solution for this sin^2x - .49=0<--- the answer has 4 different solutions
(sinx)^2 =.49 sin(x) = +/- .49 doesn't give an interval, so it has infinite solutions... if your interval is something like 0..2pi then arcsin(-.49) (two solutions) and arcsin(.49) (two more solutions)
the intervals are between 0 and 2pie
and wouldn't it be root .49 because sin is squrd?
(sinx)^2 =.49 sin(x) = +/- sqrt(.49) doesn't give an interval, so it has infinite solutions... if your interval is something like 0..2pi then arcsin(-sqrt(.49) (two solutions) and arcsin(sqrt(.49) ) (two more solutions)
but how would you find the solution would i add 3.14 to root .49 and subtract 3.14 (btw everythings in radians)
