1. If I draw a quadrant diagram and make it look like I've used my quadrant diagram to find the solutions of a trigonometry equation can I use my graphics calculator to find all the solutions to the equation?????????????????

will i lose any marks

I... what? Well, you'll need to be more specific. I think you'd lose a method mark or two depending on what exactly you're talking about.

Off-topic: but why don't you just understand the damn thing and not rely on a calculator to do it for you?

Because unfortunately, I have a life and don't have the time to sit down and try to understand Maths that I'll never use again in my life.

Now, with the pic that I attached, you can see that I've drawn a cosine graph and a quadrant diagram to make it look like I know what I'm doing. Would this be ok?

Why are you taking it at A-Level, then?

That should get you all the marks.

Sorry, took a closer look at your answer. It is incorrect. You'd only get 4/5 marks.

Understand how to solve trig equations and why x=75.5 is not a solution.

I doubt that I have to understand anything as a lot of people get very good grades just with the help of their calculators

Are you 100% sure, 75.5 is not a solution because my calculator, examsolutions and the mark scheme say it is

Urgh, sorry. Yes it is - I was looking at a dumb thing. If you got one of them wrong though, you'd lose out on both a method and an accuracy mark. Whereas if you showed the method but got the answer wrong, you'd get the method mark at least.

So, that would be full marks, yes?

I recommend you get a Graphics calculator, it will prevent you losing marks, if you look at a dumb thing in the exam

Yep.

Thank you, but I think I'll be sticking with actually understanding what I'm doing.
13. Before you do what Zacken told you to do, learn how to draw a cos graph.

It was a quick sketch calm down

By the end of it you were out of phase with a cos graph(not mentioning the non-constant amplitude).

+ I don't need to learn how to sketch anything as my calculator can do it for me
