In this problem we use mathematical induction to establish a formula for the sum 1x2+2x3+...+n(n+1). Presented by N J ... In this problem we show how to factor z^4+4 over the rational numbers. We use the fact that the complex zeroes of z^4+4=0 come ... Here we use the remainder theorem and the factor theorem to show that z-a is a factor of p(z), and find all Here we solve a polynomial equation with real coefficients, given a complex root. Presented by Thanom Shaw of the School of ... Hello we're at unsw I'm Norman wurger and we're going over some tutorial problems from our first year math 11131 Quite possibly the most important idea for understanding
We show that n sequential powers of an n'th root of unity add up to 0. This also illustrates a nice and simple method for calculating ... We look at the relation between a complex number, its complex conjugate, and its modulus squared. Presented by N J Wildberger ... Here we calculate the product of two complex numbers in polar (or modulus-argument form) as well as in Cartesian form. In this problem we calculate the modulus, principal argument and polar form for several complex numbers. Presented by N J ... Here we find the roots of a quadratics equation with complex coefficients (in Cartesian form). To do so we also need to calculate ... In this video, we'll dive into the top 10 essential concepts you need to master when it comes to matrices. From understanding the ...
We show how to find the solution of the system of
