Question

If Tan A = Cot A then find CosA ​

Answer 1

Step-by-step explanation:

tan a = cot a

sin/cos a = cos/sin a

cross multiplying,

sin² a = cos² a

cos a = √sin²a

cos a = sin a

Answer 2

Answer:

tan = cota

sin\cos a =cos\sin a

cross multiplying

sin2 a =cos2 a

cos a=√sin2 a

cos a = sin a
