no man any way it isnt possibleoh, yes, we'll have to make an eq first, right?
dont they say differentiate with respect to x in questions
you can differentiate one variable only

Some queries:no man any way it isnt possible
dont they say differentiate with respect to x in questions
you can differentiate one variable only
suppose if we have something like, y = 5cosx + 2cosyno man any way it isnt possible
dont they say differentiate with respect to x in questions

yep but how ?suppose if we have something like, y = 5cosx + 2cosy
we shall make y the subject first, no?
its very good to draw diagramsSome queries:
Shud we draw or sketch diagrams in say questions like tht of velocity and other relevant questions and also label them clarity and to refer in later part of out answer
Also in bin exp shud we write the coefficient in Combination form or column form i.e (n (above) r(below)
yes, it isnt.yep but how ?
I am pretty sure not in olevels
Thnx and is it also pertinent to draw sketches in questions like when there is a sector of circle given and a chord and since the radii form an isosceles triangle we cud find the chord by drawing a perpendicular frm the centre to the chord and then apply trig functons so we shud also draw diagrams to illustrate the perpendicular bisector as well,right?its very good to draw diagrams
dont think it matters for bin exp but use above and below if you can
its good to draw diagrams, if you make a mistake the examiner can see what you were doingThnx and is it also pertinent to draw sketches in questions like when there is a sector of circle given and a chord and since the radii form an isosceles triangle we cud find the chord by drawing a perpendicular frm the centre to the chord and then apply trig functons so we shud also draw diagrams to illustrate the perpendicular bisector as well,right?
Also in plotting str line graphs frm non linear eq shud we draw a table of values for Y and X whtever they may be evn though the question just says to draw the str line on graph?
Also for proving trig identities is there any definite rule to have followed the MS..I mean coz there may be many diff methods so wht do u reckon..will they give FULL marks if we do arrive at the solution ....any suggestion abt this which u many have heard of or suggest urselfits good to draw diagrams, if you make a mistake the examiner can see what you were doing
the table is nearly necessary for complex equations but for simple linear ones there is no need
And also abt those questions in which they ask us to draw linear graphs and thus find unknown constants .In this question since it is highly unlikely to get correct answers in higher degrees like 0.00546 or like tht shud we write the answers to 1 d.p or still 3 sig fig like 0.403 or 0.40 or 0.4?its good to draw diagrams, if you make a mistake the examiner can see what you were doing

What is the differnentiation of 5cosx + 2cosy ???
-5 sinx - 2 siny
not possible....not same variable
No this cant be ...simple as tht
Also for proving trig identities is there any definite rule to have followed the MS..I mean coz there may be many diff methods so wht do u reckon..will they give FULL marks if we do arrive at the solution ....any suggestion abt this which u many have heard of or suggest urself
Btw how is ur prep goin

Thnx a bunch

Not good at all!! but I'm still glad about my preperation...good, Alhamdulillah.
wbu?
no probs at all , the point is getting the LHS=RHSAlso for proving trig identities is there any definite rule to have followed the MS..I mean coz there may be many diff methods so wht do u reckon..will they give FULL marks if we do arrive at the solution ....any suggestion abt this which u many have heard of or suggest urself

yes you should, try putting the equation you made in calculator and test values already given with itAnd also abt those questions in which they ask us to draw linear graphs and thus find unknown constants .In this question since it is highly unlikely to get correct answers in higher degrees like 0.00546 or like tht shud we write the answers to 1 d.p or still 3 sig fig like 0.403 or 0.40 or 0.4?
Thnx a bunch
