First we follow the "times by the power and take one from the power" rule. This is the easiest way to remember how to differentiate anything.
So (3x4)x(4-1) -(2x2)x(2-1)<...
The integration by parts formula: S:udv/dx = uv - S:v*du/dx, where S: means "Integral of with respect to x"
Let 2*x be u and sin(x) be dv/dx
So du/dx =2 and v= -cos(x)
To determine which function is your u value in the by parts equation, you can use the acronym LATE to find the order of precedence for this value. LATE stands for: Logarithmic functions Arithmetric functi...
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<...
