Solve the complex equation z^3 + 32 + 32i(sqrt(3)) = 0
First thing to observe here, is that this equation is somewhat different to what you would find normally. This is a complex equation. How can you tell? The third term, ie 32i(sqrt(3)) contains the symbol for...

Integrate (3x^2+2x^-1) with respect to x in the range of K to 3 and explain why K cannot be 0
Integrated: [x^3+2ln(x)] Sub in 3 and K: [3^3+2ln(3)-k^3-2ln(k)]Simplify: 27-K+2ln(3/K)—> K cannot = 0 otherwise ln(3/k) would have an undefined value, as would ln(k)

Find the coefficient of the x^2 term in in the expansion of (1+x)^4.
To get an example of what this question is asking: the expansion of (1+x)^2 can be found by distributing and gives 1+2x+x^2. The coefficient of the x^2 term here would be 1, and for the x^1 term it would be ...

how find dy/dx of parametric equations.
We start with parametric equations of x=2t+3 and y=3t^2+3t+2. To find dy/dx, we need to work out either (dy/dt)/(dx/dt) or (dy/dt)*(dt/dx). This makes the dt's cancel each other out, allowing us to find dy/d...

Express (5x + 3)/((2x - 3)(x + 2)) in partial fractions.
To start, we understand that partial fractions are used so that we can more easily integrate a function. When you add two fractions together, you consider both denominators and find the LCM ; partial fractio...
