An easy way to integrade and differentiate simple equations is by bringing up all the denominators, in this case rewrite 3/x^2 into 3x^-2. Thus it will be easier to manipulate the powers. For Integration ...
i) Using the power rule, f'(x) = 3x2 - 6x ii) To find stationary points, set f'(x) to 0: 3x2 - 6x = 0. 3x(x - 2) = 0. x = 0 or x = 2 So the co-ordinates are (0,f(0)) = (0, 1), and ...
1/(x2) can be written as x-2
We know that to differentiate you need to multiply by the value of the old power and minus 1 from it. This means dy/dx of y=...
Put w=a+bi, z=c+di where a, b, c, d are real, and i2=-1. Then |wz|2=|(a+bi)(c+di)|2=|ac-bd+(ad+cb)i|2=(ac)2+(bd)2-2bcd+(ad)2+(c...
Fistly show that: 93x+1=3y
To find x we need to get the left hand side of the equation to be 3m(3x+1) where 3mJGAnswered by Judy G. • Maths tutor5268 Views
