I'm trying to solve an equation & find 'natural frequency' i.e. Wn. I'm using 'angle criterion' formua:
S = -0.1483 +/- 0.2143
The only way I can find to enter the '+/-' symbol into a worksheet is to drag from; Help>Quicksheets>Extra Math Symbols. But when I attempt to enter the '0.2143' on the right hand side of the '+/-' it interprets the point (.) & puts the 2143 as a subscipt. Is what I'm trying to do possible in Mathcad? If so, how?
