under root (sec A - 1) / under root (sec A +1 )= 1- cos A / sin A
Added by Nicole S.
Step 1
First, we can simplify the left-hand side of the equation using the difference of squares formula: √(sec A - 1) / √(sec A + 1) = (√(sec A - 1) / √(sec A + 1)) * (√(sec A - 1) / √(sec A - 1)) = (√(sec A - 1) * √(sec A - 1)) / (√(sec A + 1) * √(sec A - 1)) = (sec Show more…
