The formula axb = |a||b|sinθ is given in the formula bookletTherefore, θ, the angle between both vectors a and ...
First check if a, b and c all have a common factor.For example, if we have 3x²+6x+3=0, we can divide both sides by 3 and get x²+2x+1=0, which is easier to solve.If a,b and c do not all have a common facto...
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)) ...
Simultaneous equations have at least two unknowns that must have the same value in each equation. This means the value of x and y in both equations must...
From previous question y=2(x+2)2-1Minimum would be when (x+2)2 is at it's smallest value, in this case when (x+2)=0 since any other value squared would be greater than 0. This occurs...
