Solving Trig Equations on the TI-Nspire CAS

Using the solve function of a TI-Nspire CAS to solve trig equations in general and then on a specific domain. The part about the specific domain is really the point of the video. Make sure you put the restriction in the right spot!

Oh my lort! I did not even know you could do that with this calculator. I brought mine last year and using it for all my math courses. Yet, I still keep getting amazed with everything this device could do 🤯

You saved me bro I was putting the period in the parentheses <3

[cannibalfish]

Thanks man, this is exactly what I needed!

[vanessa-sbgn]

woahhh, thank you for saving my friend and i's maths mark!!!

[lisaj]

thank god i know how to solve those problems. thank you much

[yanniswesser]

how do you do this for multiple variables

[commandercody]

if u click the radient symbol on the top right corner it will be changed into degrees that will give u an exact value in terms of ur answer :)

six hundred IQ, this just saved our BC class. Cheers

[ringerthehooper]

how do i make mine give my answers i n terms of pi? i keep getting decimals

[maltesnellman]

arcsin is one step and solves this immediately

[Dev-jbru]

What am I doing wrong?



It gives me a generalised answr

I put bounds but when I try to solve, it says says that more solutions may exist and to put bounds?

[distinguishedgentleman]

saved my life man (my math teacher is useless)

[ayawnn]

I did exactly what you told to do but when i press enter it says false

A small curiosity: Solve complex x: 9x^3+3x^2+3x=0 using the TI-Nspire CX CAS calculator. In my opinion, the software for this calculator has a bug that HP Prime does not have. You can calculate X manually by entering c before Solve (Solve System of Equations ...) You can calculate X manually by entering c before Solve (Solve System of Equations ...) Number of Equations: 1(we need to cross out 2 and write 1). Unfortunately, the menu does not have this option. It should not be that there is no information about it.

Hopefully my professor lets me use this calculator on the exam lol

[hkfairbanks]

Can you tell me why this doesn't work?

tanh((0.5 ∠ 75))

[smiddim]

I enter the formula and press enter and nothing happens. what could be wrong with my CAS?
