Question

is the value of tanA=secA for all values of A​

Answer 1

Answer:

yeah mate

hope this will help u... thanks

Answer 2

Answer:

NO!!! Absolutely not

Step-by-step explanation:

You have

$sec^{2} A-tan^{2} A=1\\ So \\ sec^{2} A=1+tan^{2} A\\\\ secA=\sqrt{1+tan^{2}A }$

Thus you cannot say what you have written

It may be true for some values like A=90 degrees
