·     In a binomial probability question that only asks you for one single probability (e.g. P=48), use binompdf·     In a binomial probability question that asks you for multiple probabilities (...

Using the formula (given in the formula booklet):∫ u(dv/dx) dx = uv − ∫ v(du/dx) dxFor example if we want to integrate ∫xsin(x) we can take x to be u and sin(x) to be (dv/dx).So ∫ xsin(x) dx = x(-cos(x)) ...

I believe that to be good at integration and maths in general practice is needed. Enough practice can give the student enough knowledge to be able to solve any question. For example, integration by parts ...

The quickest way would be to find determinants of the matrix; this way we can verify whether the matrix has unique (then we can directly calculate it) solution, infinite number of solutions or no solution...

f'(x) = 3λx^2f''(x) = 6λxFor the inflection point (x₀,y₀), it is true that f''(x₀)=0 so 6λx_o=0 => x₀= 0 (since λ cannot be zero)Therefore, the inf...
