As we are told that the value of x is equal to 3, we are able to substitute this into our equation, so it becomes: 2(3)^2. We then use the rules of BIDMAS, so we must square the number 3 first (meaning we...

1 find the domain of the function (where it exist) 2 find the solutions of the function, solve f(x)=0 3 if it has vertical asyntotes (poles) identify them (eg the denomitator=0) 4 find the intesections wi...

Adenosine triphosphate (ATP for short) is used to provide the energy for many cellular functions - by both animal and plant cells - as cells are unable to source their energy directly from sugars such as...

Polar coordinates are expressed in the form (r,θ), where r is the distance of the point, P, from the origin, and θ (usually expressed in radians) is the angle between the line joining the point to the ori...

Temperature is a measure of the average kinetic energy of an object. We can approximate this average kinetic energy using the relationship E≈kT. Where k is the boltzmann constant and T is the absolute tem...
