tan(60)/cos(45) = (sin(60)/cos(60))/cos(45)
= ((√3/2)/(1/2))/(√2/2) = (√3)/(√2/2) = (2√3)/(√2)
= ((2√3)(√2))/((√2)(√2)) = (2√6)/2 = √6

If any step doesn't makes sense, hmu!

Answer:


\sqrt6

Explanation:

We are given that
(tan60^(\circ))/(cos45^(\circ))

We have to evaluate tan 60 degrees over cos 45 degrees

We know that
tan 60=\sqrt3


cos45=(1)/(\sqrt2)

Substitute the values then we get


(tan60^(\circ))/(cos45^(\circ)) =(\sqrt3)/((1)/(\sqrt2))

When a denominator in fraction then the number in the denominator of denominator fraction will convert into multiply

Suppose , we have


(2)/((2)/(3))=(2* 3)/(2)=3

Using this rule


(tan60^(\circ))/(cos45^(\circ)) =\sqrt3* \sqrt2=\sqrt6


(tan60^(\circ))/(cos45^(\circ)) =\sqrt6

Hence,
(tan60^(\circ))/(cos45^(\circ)) =\sqrt6
