i) y = x2+3x+2 = (x+3/2)2-1/4Solution for (x+3/2) = 0 is x coordinate, which is x = -3/2Solution for y value is the additional constant, which is y = -1/4Therefore the vertex (minimu...
x2+3x+2 = (x+p)2+q (x+3/2)2 = x2+3x+9/4 x2+3x+2 = (x+3/2)2-9/4+2 x2+3x+2 = (x+3/2)2-1/4
I find it is best whenever you open your maths paper to draw this diagram to help you remember: Sin(X) -> cos(X)-> -sin(X) -> -cos(X)----->{Drawn in a circle on the board} To diff...
Assume y = 2x + pi/2, Since the period of 'tangent' is pi, the general solution of 'y' to valid the equation of tan(y) = SQRT(3) is the form of y = npi+pi/3 where 'n' is any positive or negative...
a) In one week he will drive drive twice, each day the probability of getting caught is 1/100 and not getting caught is 99/100. using a probability tree diagram, we can see there is only one possible outc...
