    what is a TI-83?is that some special kind of calculator?...if it has shift all you have to do is press shift then sin(11/25)...

    ti-83 that is what he hase know ok but he need the sin and the sin is 26 but he need to plug it in the calculater.

    nah, im still trying to plug in the numbers into my calculator to end up with 26, cause the answer sheet says 26 but everything i tryed it still hasnt worked, the problem is sin X (11/25) int he end X will be 26

    then you must hit the yellow button that says 2nd before you hit the sine button...2nd is equivalent to shift...did you try that?

    God_in_me is correct - he is showing you how to access the sin^(-1) function. sin^(-1) is the inverse function of the sin function. It is also know as the Cosecant. So to solve your equation this is what your actually doing. "Solve for x... \[\frac{1}{\sin}*\sin(X)=\frac{1}{\sin}*\frac{11}{26}=(\sin^{-1})(11\div26)\]

    It's kind of like dividing both sides by 5 in this equation. \[5x=100\] But you need to know how to find the inverses of your three main trig functions.
