2x-1 = 0 is a factr means find x and put that value in eq. solvng it to = 0


now u wil gt eq. in a and b .

then another x-2 =0 is given find x here and put it in the eq. again, this time do nt slve the eq. fr = o!!! solve fr = 12 as stated that when this alue is applied remainder will be 12.

so u will gt another eq. in trms of a and b. now slve bth simul. :) hope it is clear??

Cope up boy.. it is paper time :)

Hey thanks panda222.
For graphs of sine cos and tan, can you brief me about the things that you should know about these, i mean in terms of amplitude etc...
One more thing, number 11 of same question paper. How do you do (iii)?
Thanks once again buddy.

Yes so a sine graph looks like this:

Y=sinx

sinx.gif

Y=cosx

cos.gif


Y= tanx

tanx.gif


So for the sin graph, amplitude is 1 (unless there's some other number like in that previous question). Period is 2 pie.

For cos x graph. Its pretty much same as sinx except it intercepts at 1. Same period and amplitude.

Tanx has a whole diffferent story. Just learn that damn graph. No amplitude. Period is one pie.

so u did find the gradient of the two equation so then apply the formula tanx=m.u will get two angles becoz there is 2 gradient so find the difference in angle and thats the answe

In the formula : tanx=m.u, what is 'u'?
