## PrecalculusEngineers looking for an accessible approach to calculus will appreciate Young’s introduction. The book offers a clear writing style that helps reduce any math anxiety they may have while developing their problem-solving skills. It incorporates Parallel Words and Math boxes that provide detailed annotations which follow a multi-modal approach. Your Turn exercises reinforce concepts by allowing them to see the connection between the exercises and examples. A five-step problem solving method is also used to help engineers gain a stronger understanding of word problems. |

this is the book I should have had as a student, shows the problem then how to solve it,method then easily applied to similar problems instead of the drawn-out mindless waffling ways they tried to drum into me at school in the 1960s. Only had a quick look at contents but is very understandable
