holding your paper up to the light on the other side Make sure arrows are in correct places

Case 1: the LHS becomes (2x-1) Case 2: the LHS becomes -(2x-1) the RHS doesnt really change N.B- if it is not an inequlity, u must check your answer by subbing in value.

but she could have shown u the 2nd black disk she took so wt bout like RB ,WB, BR, BW, BB etc.. :( thx

Ok thx, what about this one A bag contains one red disk, 2 black and 1 white Kathy selects one and keeps it hidden, then selects a second and keeps that also hidden if kathy shows us one disk is black. What is the probability that the disk that is still hidden is black. Ans is1/3 but i agn...

A box contains disk which are numbers 2,2,3,3,3,4,5. Daniel takes one disk at random from the box, then takes another without replacement. what is the probability of the second disk being a 2 (ans is 11/42) i keep getting 12/42, i think i may be doing sth rong? please help and explain. :D

Draw a circle with 10 boxes around it allow the first Man to sit down, His wife has only one selection of a seat to sit in for the second man...he can sit anywhere is the 8 seats remaining and his wife hence has only one selection the thrid man then has 6 seats to choose, wife has 1 again...and...

Hey min? Its pretty much CALCULUS ignoring the Us so its 6!/(2!2!) / 5040 where 8!/2!2!2!= 5040

Its number (1) yeah my bad Yes i am scardizzle, who are u?

oh sorry i think i left out substitution by letting u=sinx

The answer is -(2-sin(^2) x)^0.5 + C i think you did something wrong

I need help understanding this question I have the teachers solution but i dont understand the actual integrating part Int (cos x sin x) / (2-sin(^2) x)^-0.5 dx ie. i dont get the part where you: [ Int u(2-u^2)^-0.5 du ] please explain. thx in advance

Taken from a Trial: A missile is released from a plane flying horizontally at a height of 500 m and at a constant speed of 300m/s (i) Show that the equation of the horizontal component of the subsequent motion of the missile is given by x=300t, where t is time and x is horizontal displacement...
