Have you got the answers to these? If so, could you please put it up.
No, just put the sheet together on friday. I was planning going over it in class. Do you have any specific questions on it?
Just for question 5. I got a reasonable angle, but when I put it in Pi form it gets weird. My answer for 5 was X= 47(Pi)/120 , 193(Pi)/120
Seems like such a strangle number to be, so I was hoping to check to see if it was right. I did try and desmos and they seem to agree, but I feel the need to check further, just in case.
Answer to question 5 is 1.231, 5.052 radians to 3d.p. (1 d.p. acceptable).
In calculator paper you can use decimal radians if not giving ‘common’ fractions of pi.
I got the same answer as that, just in a different form. Would I still gain the marks?
Should do but at the level you are aiming for it would be good to recognise which is a more appropriate form for your answer in this case.
Can you put the solutions for the Area between curves sheet online please?
