Ok Well, I need a lot of help with this. I hav eso many problems to do and I do not even know where to start.
I just want to get help with a few and then I'll see if I can figure out how to do them on my own..
Ok so here is the first type of problem I have.
Solve each trig equation.
First off I'm not entirely sure what I'm trying to find in the following. Even then I don't really know where to start.
1. sin x = -sqrt2/2
2. Cos 2x=-sqrt2/2
3. tan .5x= sqrt3
4. sqrt3 sec x +2 =0
I think if i know how to do those I will be able to figure out the rest of those type of problems.
Here id the other type of problem i have to do.
Solve the each trig equation
1.4 sin^2 x-3=0
For this one would I just add 3 then divide by 4. Then take the inverse sin of sqrt of 3/4 and the answer would be 1.047. If that is right then that would be one of the solutions but Im not sure how to find the other one
2. cos x +2= 3cos x
3. 2 sin ^2 x-3=0
thanks for the help guys.
I did some of the problems and I wanted to see if i got the right answer for them.
I wasn't able to get these 2.
Also how do I show that an equation has an infinite amount of solutions
