Thread: Ti-nspire cas trig equations

How do i solve trig equations on this? And also factoring.

It seems the calc doesnt recignie cos^2_x keeps saying missing (

I want to factor and solve for x by putting in cot x cos^2x-2cot x

How do i put it in?

Thanks!

With most CAS is written as

Thank u so much!

Also, how would i graph if im given,

Vertex (4,-1); point (2,3)

I know how to graph but smetimes i messup with signs and i screw up the whole graph.

is the graph a parabola?

Yes.

you should be familiar with the vertex form of a parabola ...



sub in the given vertex coordinates and the coordinates of the given point ... solve for , then graph.

btw ... next time state what you are graphing. if you had not mentioned a vertex, I would've had no idea what you wanted graphed in the first place.

Yes, i realized that, sorry.

I know how to graph on paper, i just wanted to know how to graph on the calc so i can verify my ans.

Thanks.

Thanks.

have you taken a look at the owner's manual?

no
