# How do i type in sine squared into my graphing calculator?

I need to solve a problem with a sine squared by graphing, i forgot how to plug that into my calculator. thanks.

• Aye, the TI-84 Plus doesn’t have a sin² feature. However, sin(x)² will have the same result (because it’s the same thing).

• Keep in mind that Sin squared actually means (sin (x))^2. If you type this into your calculator, it will give you the value you’re looking for.

• Go to mode on your calculator Go to Pol in mode and click on that then push y= type in 4sin(4x) *the x button will enter theta, but it’s still the same button* it will come up with interesting stuff that way. Better than function equations because well.. they aren’t functions.

• It means you square whatever the sine (answer) is. For example sin^2 60.0 degrees would be sin 60.00=0.866 then you square 0.866 so the final answer would be 0.750 I confirmed with my professor.

• you can’t

that will produce an error.

i suggest you just square the whole equation. it will yield the same results.

• just type in (sin (x))^2 into Y1=_____.

Hope this helps!
