Question

Help is appreciated(: How would I solve 2cosx+5=4?

Answer 1

you want to solve for cos x?

Answer 2

I believe so.

Answer 3

Subtract 5 from both sides, you get 2 cos x = -1

Now divide both sides by 2, you get cos x = - 1/2

Answer 4

thanks! so for 1/2-sinx=1, would I have to subtract the 1/2? @Easyaspi314

Answer 5

Yes, but then you get - sin x = 1/2

Then you have to divide both sides by -1, so you get sin x = - 1/2

Answer 6

Okay, thanks again(:

Answer 7

sure.
