Many Spanish words have accent marks (e.g. móvil, habló or fantástico). While this seems odd for english speakers, the rules followd in Spanish are suprisingly straightforward!<...
When you evaluate a definite integral, we can think about using the "+C" and see what happens. Let's take (INT)2x dx between 2 and 3. We then have [x2+C] between 2 and 3. For x=3 we h...
Differentiate x = u2 to get dx = 2u du. We need to change the limits, too:
1 <= x <= 9 <==> 1 <= u2 <= 9 <==> 1 <= u <= 3 (since we are give...
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 tutor5751 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 tutor4850 Views
