s- integral s ln (2x+1)dx ? = ln(2x+1)x - s x d( ln (2x+1)) = ln(2x+1)x- s x [(2x+1)'/ (2x+1)] dx = ln(2x+1)x- s x [(2)/ (2x+1)] ?... then i'm confused... "ln(2x+1)x- s x [(2)/ (2x+1)] ?... then i'm confused..." x [(2)/ (2x+1)] = 2x/(2x+1) = (2x+1-1)/(2x+...

s- integral s ln (2x+1)dx ? = ln(2x+1)x - s x d( ln (2x+1)) = ln(2x+1)x- s x [(2x+1)'/ (2x+1)] dx = ln(2x+1)x- s x [(2)/ (2x+1)] dx = ln(2x+1)x- s (2x/2x+1) dx = ln(2x+1)x- s [(2x+1-1)/(2x+1)] ... i'm confused about why there is a minus 1 after the integr...

s- integral s (p^5) lnp dp ? = (lnp)[(p^6)/(6)] - s (i'm confused here) Let ln p = u and p^5 dv = dv du = 1/p and v = p^6/6 The integral can be written uv - v du = (ln p*p^6)/6 - S (p^5/6) = (1/6)ln p*p^6 - ??? Complete the last step

How do i do this question using the binomial theorem concept? It says, expand (2+x)^5 up to x^2 term, hence, expand (2 + x + x^2)^5 up to the x^2 term. I could do the first part, and the answer would be (32 + 80x + ...) But how should i make use of the an...

Question: Find the first 3 terms in the expansion, in ascending powers of x, of (2 + x)^6. Hence, obtain the coefficient of x^2 in the expansion of (2 + x - x^2)^6 I know the first part of the question, and the first 3 terms are (64 + 192x + 240x^2 + ...)...

weight = mass * gravitational field strength. weight depends on location, mass does not. mass on mars IS THE SAME AS mass on Earth

car: velocity = 20/2 m/s = 10 m/s momentum = mass * velocity = 3000*10 kg x m/s player: mass = momentum/velocity = 1120/10 = 112 kg.

total mass = m1+m2 = 3 down force on m1 = 9.8 (m1.g) fric force on m2 = 2*9.8/4 = 9.8/2 (m2.g.mk, cuz mk = 0.25 = 1/4) net force = 9.8 - 9.8/2 = 9.8/2 a = net force/total mass = 9.8/2/3 = 1.6 :)
