Question

If tan A = cot A then find cos A.​

Answer 1

Answer:

First let me clear the basics if tan a= tan b. Then a and b are related as a =n * pi + b

Coming back to the question, if tan a equals cot a then tan a = tan (pi/2 — a)

Using the first said relationship

a = n* pi + (pi/2 —a) on simplifying it

a = n*pi/2 + pi/4

Plugging in integral values for n would give the solutions of a and then find sin a for that angle.

P.S : All angle above mentioned are in radians.
