Question

if tan A=√3then cot A=?
​

Answer 1

Answer:

As here

tanA=√3

A=60

now

tan2(60)

tan120

tan(180-60)

According to class 11 property

tan(-60)        

-tan(60)

=-√3

But in 10th class the value of Ф cannot be exced from 90 so whenever we get a number more than 90 we have to divide by 2 and write down the value

Answer 2

Answer:

1/√3

Step-by-step explanation:

Given- tan A= √3

To prove- cot A

Proof- tan A = P/B

√3 = P/B

cot A = B/P

1/√3 = B/P
