1. The problem statement, all variables and given/known data
A salmon starts 2.00 m from a waterfall that is 0.55 m tall and jumps at an angle of 32.0. What must be the salmon's minimum initial speed to reach the waterfall.

2. Relevant equations
$$\Delta$$y=visin$$\Theta$$$$\Delta$$t+1/2g$$\Delta$$t2

3. The attempt at a solution
I have tried all the related formulas for projectile motion, and I felt like I got somewhere a few times. But the results aren't really checking with a graphing calculator.

You need to show your work in order to get help here.

What have you tried so far? And what exactly does the graphing calculator not agree with?
