Question

1. If cos =2x ÷1+× square than tan=​

Answer 1

Answer:

$\frac{ \sqrt{1 + 2x- 3{x}^{2} } }{1 + {x}^{2} }$

Step-by-step explanation:

In a right angled triangle, we know that, cosine is the ratio of adjacent side to hypotenuse. And, tangent is the ratio of opposite to the adjacent. by using pythagorous theorem, we found out the value of opposite as

$\sqrt{1 + 2x - 3 {x}^{2} }$

so, tan

$= \frac{ \sqrt{1 + 2x - 3 {x}^{2} } }{1 + {x}^{2} }$
