Hello and welcome to MathHelpForum.
You should understand that this is not a homework service nor is it a tutorial service. Please either post some of your own work on this problem or explain what you do not understand about the question.
I am new here by the way, I have a small problem for a question I can complete in Compound Angle identities
sinθ = tan (θ/2)(1 + cosθ)
Look forward to the answer. I can almost work it work it out but I get stuck somewhere near the end.
I actually did it, and got to the same stage and over it but got lost because I had no confidence. This is where I gave up because I thought it would never end up as sinθ.
So this is correct?
Thanks a lot. I have another similar question. I will try to work it out first see whether I get then I will submit it.
