Let α and β be bounded measurable functions on the unit circle 𝕋. Then the singular integral operator Sα,β is defined by Sα,βf = αP+f + βP–f, (f ∈ L2(𝕋)) where P+ is an analytic projection and P– is ...
Rearranging the formula for the circumference of a circle makes the radius the subject. Start with the new subject and write out the function machine for the formula, showing each operation step by ...
