We want to prove:
alogb(c) = clogb(a).
Recall that we can always write x = eln(x), so xy = (eln(x))yTDAnswered by Tutor69809 D. • Maths tutor5641 Views
Remeber the formula: (a - b)2 = a2 - 2ab + b2. Notice that y = x2 - 23x + 5, so we want to write this using (x - 3)TDAnswered by Tutor69809 D. • Maths tutor4791 Views
a) u is perpendicular to w, so u • w =0. This means that 23 + 3(-1) + (-1)*p = 0, so 6-3-p=0, hence p=3. b) The magnitude of v ...
2x +3 + (4x-1)/2 = 10 The divisor (2) is the biggest problem right now so we need to get it on its own...
(4x-1)/2 = 10-2x-3 Equation has been rearranged!
We will call the integral I, so I = integral of 1/(3+(x+4)1/2) dx between 0 and 5. First substitute u=3+(x+4)1/2 into the equation to get I = integral of 1/u dx between 0 and 5 Next ...
