The pancreas contains beta cells of the Islet of Langerhans which produces a hormone called insulin. Insulin is responsible for lowering the concentration of glucose in the blood. In type 1 diabetes, not eno...

Generally, quadratic equation of the form $\color{orange}{a}x^2 - \color{blue}{b}x + \color{green}{c} = 0$ where $\color{orange}{a} \neq 0$ can be solve by evaluating $$\color{brown}{\Delta} = \color{blue}{b...

In bullet points: The bill system allows for UK legislation brought forward by the government to be debated in both the House of Lords and Commons where amendments can be put forward and all legislation is d...

At first this equation seems tricky, but we can perform a clever substitution to simplify it. We notice that if let y = 2^x, then we can rewrite this as: 8(y^2) - 9y + 1 = 0 This now becomes a simple quadrat...

Complex numbers have three primary forms: the general form, z=a+ib; the polar form, z=r(cosθ+isinθ); and the exponential form, z=rexp(iθ). To convert from the general form to either form you need to find r a...
