WebFor any two differentiable functions, the derivative of the quotient of two functions is the denominator times the derivative of the numerator minus the numerator times the derivative of the denominator, all divided by the denominator squared. ... The derivative of sin(\theta ) is cos(\theta ), and the derivative of cos(\theta ) is −sin(\theta ). In mathematics, theta functions are special functions of several complex variables. They show up in many topics, including Abelian varieties, moduli spaces, quadratic forms, and solitons. As Grassmann algebras, they appear in quantum field theory. The most common form of theta function is that occurring in the … See more There are several closely related functions called Jacobi theta functions, and many different and incompatible systems of notation for them.
