This question is asking us to split up the fraction into two separate fractions.To begin we use one of the standard forms for solving partial fractions, this is (A/(X+1))+(B/(X+2)).To solve set the first ...
We can immediately see that more than differentiation rule will be needed here. The expression in question is the product of two smaller expressions, so the product rule may be useful. But to apply the...
These cubic equations are usually fairly simple once the method is known, firstly make the right hand side (RHS) equal to zero by subtracting 1 from both sides:
x^3+4x^2+x-6=0
...
First step I would take would make it look less intimidating by converting all components into sin and cos i.e
2(((sinx)/(cosx))^2) + 1/((cosx)^2) = 1
Notice that there is a...
Log rules:
log(a) + log(b) = log(ab)
so, in this case, we must find x such that 7x = 21
thus x = 3
similarly, log(a) - log(b) = lo...
