His work set the stage for thc arrival of complex numbers Research the history of complex numbers. How were the works of Rafael Bombelli, Jean Robert Argand, Lconhard Euler, and Abraham de Moivre significant in the development of complex numbers? Write a paragraph or to about your findings.A Bitter Dispute With the publication of Ars Magna, a dispute intensified between Jerome Cardan and another mathematician named Niceolo Fontana, otherwise known as Tartaglia. What was the dispute, and how did it arise? In your opinion, who was at fault? Write a paragraph or two about your findings.If cos=35 with in QIV, find the values of the remaining five trigonometric functions for .2CLT3CLTHeight of a Tree An arborist needs to measure the height of a giant sequoia tree. He moves some distance along the ground from the base of the tree and measures the angle of elevation to the top of the tree, which is 79.0. He then backs up another 40.0 feet and measures the angle of elevation to be 72.6. Find the height of the sequoia tree(Figure 1).5CLT6CLT7CLT8CLT9CLT10CLT11CLT12CLT13CLT14CLT15CLT16CLT17CLT18CLT19CLT20CLT21CLT22CLT23CLT24CLT25CLT26CLT27CLTConvert the point (4,225) to rectangular coordinates, and state two other ordered pairs in polar coordinates that name the same point.29CLT30CLTFor Questions 1 through 8, fill in each blank with the appropriate word or expression.
