7.0588 = sin(10.4*∏*t)

how do i transpose this to solve the equation finding a value for t?

thanks

your casio is ok because the sin of ANY angle must not be greater than 1.

X=a*Sin(omega*t)

where x = 0.6m

a = 0.085m

omega = 10.4*Pi

0.6=0.085*Sin(10.4*Pi*t)

any ideas mate?

Actually, no, what you posted wasn't the full problem. Why is x = 0.6 m? Why is a = 0.085 m? What situation does this equation model? You need to post the entire word problem. It's possible you plugged in the wrong values for the variables.hmmm here is the full problem, i thought i could solve it with the first question.

The equation you wrote is easy to deal with: it has NO (real) solutions. That is because you are asking to have a value of "sine" that is > 1, and that cannot happen for any real angle.

However, it does have solutions in the complex plane; one is t = 0.0480769 - 0.080874I, where I = sqrt(-1).
