Question

SecB=3/5 for some ∠B.State whether the given statement is true or false. Justify your answer.

Answer 1

$secb = \frac{3}{5}$ can't be less than one hence this statement is false

because the minimum value of secb is 1. but 3/5 is less than one hence this statement don't support the argument.hence false.Or in the other point of view if

$secb = \frac{3}{5}$ then $cosb = \frac{5}{3}$ which is greater than one.We, know the maximum value of cosb is one.

which proves above statement is false.
