Question

if right triangle ABC,right angled at B,if tan A=1,then find the value of 2sinA cosA/cotA​

Answer 1

Answer:

answer is 1

Step-by-step explanation:

as we know sin 2a = 2sinA cos A= 2 tanA/ 1 + tan^2 A

substitute the numerator with 2 tan A/1+ tan^2 A

and solve the equation by the value of tan A given which is 1.
