1. Sin 70 degrees cos 40 degrees - cos 70 degrees sin 40 degrees

2. cos^-1

3. Solve cos2A=0 on the interval 0 is less than or equal to A which is less than or equal to 2pi?

4. A=35 degrees and side a=5

5. Side a=3 and side b=1

PLEASE SOLVE THESE HARD QUESTIONS FOR ME don't just give the answers!! Do this for me and I have no clue even for the basics of pre calculus and I never opened the book and this is due todayyyyyyyyyyyyyyyy

Why are you doing this if you have no clue? Do you know trig? Who says it is due today, and why if you haven't studied it?

Do this for me and I have no clue even for the basics of pre calculus and I never opened the book and this is due todayyyyyyyyyyyyyyyy. WELLLLL this is a help desk, not a homework do deskkkkkkkkkkkkkkkkkkkkkk.

Can't figure out other homework, either - https://www.askmehelpdesk.com/histor...on-669595.html.

Anyone feeling like preparing a paper? Not me.

Love you, WG, but is OP going to share his/her grades with you - https://www.askmehelpdesk.com/writin...ms-664649.html

Add the insult to Curlyben and the request that you do the homework offsite and I think this person is pushing the boundaries - "YOu didnt really answer my question earlier. I asked if I can give you my email and then via word, you and I can work assignments out together??? PLEASE? I have so many assignments to complete and they are so hard for me and I need some assistance.....do you mind chatting by email?" https://www.askmehelpdesk.com/books-...ml#post3147950

He's being homeschooled but I haven't figured out if his teacher/parent is loading him up with impossible assignments or if he just isn't applying himself. I'm beginning to reach a conclusion...

I'm wondering why he posted pre-calc questions but has no clue how to do them. Teacher's fault or student's fault? Why is he doing pre-calc??

For that matter, why not do your own English and history homework?

I do note that OP's post about homeschooling is a great explanation WHY homeschooling should be very closely supervised: https://www.askmehelpdesk.com/home-s...-663457-2.html

I have friends who homeschool and their children are LIGHT years ahead of public school children.

Back again today - https://www.askmehelpdesk.com/math-s...ns-670046.html

Kite - to help get you off the ground I will offer the following hints:

1. Consider the formula for sin(a-b), where a = 70 degrees and b = 40 degrees.
2. This one is incomplete as written. "cos^-1" means "arccosine," but arccosine of what?
3. Start by thinking for what angles does cos(x) = 0? Can you identify a few for us?
4 and 5 : are both incomplete as written.
