m=3
y1=1
x1=2
y-y1=m(x-x1)
y-1=3(x-2)
y-1=3x-6
y=3x-5
at the x-axis, y=0.
Sub in to find the x co-ordinate:
0=3x-5
x=5/3. Hence the c...
First we write the fraction in terms of partial fractions with two unknown numerators, A and B, as follows: (x+2)/(x+1)2 = A/(x+1) + B/(x+1)2
Note that since the denominator o...
now for any integral the method to deal with it is look for the easiest method, things can get trickier later down the line but always start by looking for the easy solution. this example allows us to see...
This is a good exercise to introduce student to the idea of derivatives and their possible practical use. Firstly, I should draw the cone and notice that its volume is equal to 1/3piH*RMKAnswered by Max K. • Maths tutor3700 Views
First, recognise that the function is a fraction and recall the quotient rule. y=u/v dy/dx=(vu'-uv')/v2, where u' and v' is the derivative...
