In differentiation you multiply the coefficient of the subject (what the value is multiplied by e.g. 3 is the coefficient of 3x6) by its exponent (the power that the value is raised to e.g. ...
This question is really straight forward
By using the Chain rule: f'(x) = uv' + u'v.
let u=3x, so u'=3
let v=(2x-1)^2, so v'=2x2(2x-1)=8x-4
Now, ...
You must be careful with these sorts of questions as although 1/(5-2x) is equivalent to (5-2x)^-1, when you integrate you would add one to the power and divide by the new power. But if you were to add one...
First we state the formula for sin(x+y)
sin(x+y) = sin(x)cos(y) + cos(x)sin(y)
Letting y = 2x
sin(x+2x) = sin(x)cos(2x) + cos(x)sin(2x)
Now sin(2...
Using integration by parts, we can re-write the integral of ln(x) as (xln(x) - int(x(1/x))) = x*ln(x) - x
Therefore, evaluating between 2 and 4 gives us (4ln(4) - 4) - (2Answered by Kyle R. • Maths tutor3325 Views
