Incline is at θ where sin θ = 1/20 and mass of the car is 800kg and v is 12.5 m/s
Up the road: Power = Fv F = R + (800g)/20
...
Let u = ln(x) and dv/dx = x
Thus du/dx = 1/x and v = x2/2
Using the formula:
Integral of udv/dx = uv - Integral of v*du/dx<...
When differentiating a function that is the sum of three different parts we can differentiate each part separately:
a) 2x3 is easy to differentiate. We remember the rule d/dx[axbSPAnswered by Seth P. • Maths tutor5722 Views
- First start by examining the equation. Is it in a recognisable form e.g. the equation of a circle/elipse etc. - If not, is it in the form y = or x = (these are the most common ...
LHS: because alnx = lnxa, 2ln2x = ln(2x)2 = ln4x2
Now, because ln and e are inverse functions, we take both sides to the power of e. Therefore:
eln4x^2 ...
