There are only a few cases that the calculator has to be switched to degree mode (see ex. 1,11,12&14). Example#3: Convert 57.762º to DMS. 1. Type and press . Don't use the º function here since the ►DMS function expects degrees and the º would convert it to radians...
9.2 Problem 5 Inverse Tangent The inverse tangent (arc tangent or 𝑡𝑎𝑛 −1 ) is the measure of an acute angle whose tangent is x. The relationship of sides used is opposite to adjacent. The calculator has an inverse tangent function. Only used to find the missing angle. 9.2 Prob...
Being in the wrongmode(e.g. being in degree mode when you should be in radian mode) Trusting the calculator more than your brain. The calculator will not always give you the correct sign (+ or −). Often you need to figure that out for yourself. Always estimate your answer first so...
