Question

if tan theta=cot theta then the value of 2 tan theta+cos 2 theta is​

Answer 1

$tan\alpha  = cot\alpha \\   \alpha  = (4n+1)\pi /4\\\\tan\alpha +cos2\alpha \\= tan[\frac{(4n+1)\pi }{4} ] + cos 2[\frac{(4n+1)\pi }{4} ]\\= 1 + 0 = 1$

Answer 2

Answer:

1

Step-by-step explanation:

tana=cota
